3-Fluoro-2-methylbenzeneboronic Acid CAS 163517-61-1: Product Specifications and Buying Guide
3-Fluoro-2-methylbenzeneboronic acid, CAS 163517-61-1, is an arylboronic acid used as a building block in organic synthesis, including Suzuki–Miyaura cross-coupling research and process development. Its molecular formula is C7H8BFO2, and its calculated molecular weight is approximately 153.95 g/mol. Buyers should confirm the offered grade, assay, analytical documentation, packaging, and availability with the supplier rather than assume these details from the product name alone.
This guide is for procurement teams, medicinal and process chemists, and chemical distributors evaluating the material for a defined project. We explain which specifications to request, how to assess application fit, and what to clarify before placing an order. At Maison Chemical, we encourage buyers to provide their required quantity, quality criteria, destination, and documentation needs so that we can respond with product-specific information.
Key Takeaways
- Confirm identity using the full chemical name, CAS number 163517-61-1, and molecular formula C7H8BFO2.
- Request a lot-specific certificate of analysis and clarify the analytical methods used for identity and assay.
- Evaluate suitability against the intended reaction, route, and downstream impurity requirements; do not treat a general product listing as a guarantee of reaction performance.
- Ask the supplier to confirm current availability, MOQ, lead time, packaging, shipping conditions, and document options for your destination.
Product Overview and Chemical Context
This compound is a substituted phenylboronic acid: its aromatic ring bears a fluorine substituent, a methyl substituent, and a boronic acid group. In synthesis planning, the boronic acid functionality can serve as the organoboron coupling partner in carbon–carbon bond-forming chemistry, subject to the chosen catalyst, reaction partners, and conditions. The fluorine and methyl substituents remain part of the aryl structure and may be relevant to the properties of the target molecule.
The molecular weight of approximately 153.95 g/mol is a calculated identity-related value, not a measure of purity or quality. It can help chemists calculate molar quantities, but it does not replace a lot-specific assay or identity test. Buyers should also ensure that the supplier’s documentation uses the same positional isomer and CAS number, since closely related substituted arylboronic acids are not interchangeable by name alone.
Specifications to Confirm Before Purchase
Identity, Assay, and Analytical Evidence
Ask for the product specification and a representative or lot-specific certificate of analysis before ordering. The documents should identify the material clearly and state the assay or purity result, the test method, and any applicable acceptance criteria. Depending on the supplier’s quality system and the product offering, supporting identity data may include techniques such as NMR, mass spectrometry, or chromatographic analysis; confirm which records are actually available for the lot.
Do not infer a numerical purity grade from the chemical name, CAS number, or a general catalog description. If your process has a minimum assay or limits for specific impurities, state those requirements in the inquiry and ask whether the offered material meets them. Where a particular analytical method is required for internal release, confirm method compatibility before purchase rather than after delivery.
Physical Description, Packaging, and Handling
Request the supplier’s current product specification and safety data sheet for information on appearance, handling, storage, and transport. These details should be verified against the actual offered grade and applicable shipping route; avoid relying on generic descriptions when defining laboratory or plant procedures. Keep packaging integrity, labeling, and lot traceability in scope, especially when the material will be received into a controlled inventory system.
Clarify the net quantity per container, the available packaging options, and whether the supplier can support your required pack size. For quote comparison, buyers may request illustrative quantities such as 1 g, 10 g, and 100 g; these are planning examples only and do not indicate Maison Chemical’s stock, MOQ, or standard pack sizes. Ask for the actual available quantity and commercial terms for your order.
Matching the Material to an Application
For coupling applications, assess this boronic acid in the context of the complete reaction rather than evaluating it in isolation. The electrophile, catalyst system, base, solvent, water content, temperature, and reaction time can all influence conversion and impurity formation. A literature procedure or supplier description should therefore be treated as a starting point for technical assessment, not as a performance guarantee for a different substrate or scale.
For medicinal chemistry or early-stage discovery, the key buying priorities may include identity confidence, manageable quantity, and documentation suitable for internal research records. For process development or commercial planning, buyers may place greater emphasis on batch consistency, impurity profile, supply continuity, packaging, and change notification practices. Define which of these factors are critical before comparing offers, since the lowest quoted price may not address the most important project requirement.
Buyer Selection Framework
1. Define the Required Grade and Acceptance Criteria
Start by specifying the intended use and any minimum assay, impurity limits, or analytical methods required by your organization. If the material is for route scouting, your requirements may differ from those for a regulated or tightly controlled process. Share the criteria with the supplier in writing so that the quotation and proposed documentation can be evaluated against the same requirements.

2. Compare the Full Commercial Offer
Request a quotation that separates product price from freight, packaging, and other applicable charges where possible. Confirm the offered quantity, MOQ, quotation validity, estimated lead time, and shipping terms; these may vary by destination, order size, and current availability. If timing is critical, ask whether the lead time refers to dispatch or delivery and whether any export or import documentation is needed.
3. Review Documents and Traceability
Before purchase, confirm which documents can accompany the shipment, such as an SDS, certificate of analysis, and commercial shipping paperwork. Ask whether the certificate will correspond to the supplied lot and whether the lot number will appear on the packaging and documents. If your company requires additional declarations or a specific document format, raise that request before the order is confirmed.
4. Check Logistics and Storage Requirements
Use the supplier’s SDS and shipping guidance to establish appropriate receiving, storage, and handling procedures. Confirm packaging suitability for the shipment route and the receiving site’s requirements. If the product will be held for an extended period, follow the supplier’s stated storage guidance and retain the original lot and packaging information for traceability.
Pricing, MOQ, and Lead-Time Considerations
The price of a specialty intermediate can depend on order quantity, grade, packaging, availability, and destination. A small research quantity and a larger production-development requirement may be quoted under different commercial conditions, so compare offers at equivalent quantities and specifications. Do not assume that an online listing provides a current price, confirmed inventory, or a fixed MOQ.
Lead time should be confirmed for the specific order rather than estimated from a generic product page. Ask whether the material is available for immediate dispatch or requires preparation, and request an estimated delivery window for your destination. For project planning, include time for documentation review, shipment, receiving inspection, and any internal qualification testing.
Supplier Evaluation Checklist
When evaluating Maison Chemical or another supplier, use a consistent checklist to compare product and service details. The following questions can help identify gaps before a purchase order is issued:
- Does the quotation identify 3-Fluoro-2-methylbenzeneboronic acid and CAS 163517-61-1?
- Are the offered assay, specification, and analytical documentation clearly stated?
- Can the supplier confirm the actual lot, available quantity, packaging, and estimated lead time?
- Are shipping terms, destination requirements, and requested documents included in the discussion?
- Can the supplier address questions about specification alignment and documentation before order confirmation?
At Maison Chemical, we can review your requested specification and provide a quotation based on the quantity, destination, and documentation requirements you share. Availability, MOQ, lead time, and supporting documents should be confirmed for each inquiry. This approach helps both parties identify mismatches early and supports a clearer purchasing decision.
Common Buying Mistakes to Avoid
One frequent mistake is treating a matching CAS number as sufficient proof that every commercial detail meets the project’s needs. Identity is essential, but assay, impurities, documentation, packaging, and lot traceability also matter. Another risk is comparing prices without checking whether the quoted grades, quantities, and delivery terms are equivalent.
Buyers should also avoid assuming that a published reaction example guarantees a particular yield or performance in their own process. Reaction outcomes depend on the full experimental system and may require optimization. If a specification or document is mandatory, make it a written condition of the inquiry instead of relying on an informal assumption.
Conclusion and Next Steps
3-Fluoro-2-methylbenzeneboronic acid CAS 163517-61-1 is a substituted arylboronic acid that can be considered as a building block for suitable organic synthesis applications. Its formula is C7H8BFO2, with a calculated molecular weight of approximately 153.95 g/mol, but those identity details alone do not establish the grade or suitability of a supplied lot. Before buying, verify the specification, assay, analytical evidence, packaging, availability, lead time, and destination-specific documentation.
