2,4-Difluoro-3-methoxybenzoic acid, CAS 178974-97-5, is a substituted aromatic carboxylic acid used as a specialty chemical intermediate. Its identity is defined by a benzoic acid structure bearing two fluorine substituents and one methoxy substituent; the molecular formula is C8H6F2O3, with a calculated molecular weight of approximately 188.13 g/mol. For procurement, buyers should confirm identity, assay, impurity profile, packaging, and delivery terms against the requirements of their synthesis or process. This guide explains the specification fields to request, how to assess supplier offers, and what information to include in an inquiry to Maison Chemical.

This guide is intended for procurement teams, process chemists, research organizations, and chemical manufacturers evaluating 2,4-Difluoro-3-methoxybenzoic acid as a starting material or intermediate. It is useful when preparing a request for quotation, comparing supplier documentation, or aligning a purchasing specification with a development process. It does not replace a process-specific technical assessment or the buyer’s quality and regulatory review. Buyers should verify that the material and its documentation meet the requirements of their own application.
The product is an aromatic carboxylic acid with two fluorine atoms and one methoxy group attached to the benzene ring. The CAS Registry Number provided for identification is 178974-97-5, and the molecular formula is C8H6F2O3. The molecular weight of approximately 188.13 g/mol is calculated from that formula and is a useful reference for stoichiometric calculations. Buyers should still use the supplier’s batch documentation and their approved identity tests when releasing received material.
Because the molecule combines an aromatic ring, fluorine substituents, a methoxy group, and a carboxylic acid, it may be evaluated as a building block in multi-step organic synthesis. Its suitability depends on the intended reaction sequence, reaction conditions, and impurity tolerance of the downstream process. A structural description alone does not establish performance in a particular route or confirm suitability for a regulated end use. We recommend discussing application-specific requirements with your technical team before fixing a purchasing specification.
A supplier’s offer should distinguish confirmed product data from buyer-requested acceptance criteria. The identifiers below describe the named compound, while batch-specific properties such as assay and appearance should be confirmed in the current specification or certificate of analysis. Do not assume an assay, impurity limit, or storage condition from the product name alone. If a limit is important to your process, include it in the inquiry and request written confirmation of the available grade.
| Specification item | What to request or verify | Why it matters |
|---|---|---|
| Identity | Product name, CAS number, molecular formula, and an appropriate identity test | Helps confirm that the offered material matches the purchasing description. |
| Assay | Reported result, analytical method, and agreed acceptance limit | Supports material assessment and process calculations. |
| Related substances | Impurity profile or specified impurity limits, where relevant | May affect downstream reaction control, purification, or internal release. |
| Moisture and appearance | Applicable test methods and batch-specific results, if required | Provides additional information for handling and process planning. |
| Documentation | Available batch documents and shipping or safety information | Allows quality and logistics teams to complete their own review. |
Numerical limits should be agreed rather than inferred. For example, a buyer might request an assay target of at least 98.0% or a water limit of 0.5% or less as an initial discussion point, but these are illustrative purchasing criteria—not confirmed product specifications or a representation of an available batch. The appropriate limits depend on the intended use, analytical method, and supplier capability. Ask the supplier to confirm whether the requested values can be met and reported for the offered lot.
Start with the material’s role in your process: exploratory research, route development, scale-up, or established production. Early-stage work may prioritize availability and a fit-for-purpose specification, while a production process may require tighter impurity controls, defined analytical methods, and batch-to-batch consistency criteria. These priorities should be set by the buyer’s technical and quality teams. A supplier can discuss available options, but the buyer remains responsible for confirming suitability for the process.

Consider how the material will be received, tested, stored, and consumed. A small evaluation quantity can help a team assess fit before placing a larger order, provided the quantity and packaging are commercially available. For scale-up, confirm whether the quoted quantity can be supplied as one lot or multiple lots, and clarify how batch documentation will be provided. If you have a downstream impurity limit or a specific analytical method, share it before quotation so the supplier can assess the request.
When evaluating offers, align the product identity, requested assay, impurity requirements, quantity, packaging, destination, and delivery schedule. A lower unit price may not represent a comparable offer if the grade, documentation, or shipping terms differ. Ask each supplier to identify assumptions or exclusions in the quotation. Record the confirmed specification alongside the commercial terms to support a clear purchasing decision.
Request the documents available for the specific product and lot, and review them through your internal quality process. Confirm which results are batch-specific and which are standard product information. For any critical test, ask for the method and reporting format rather than relying on a general statement of quality. Clear responses to technical and logistics questions are also useful indicators when planning a supply relationship.
Pricing for a specialty intermediate is quotation-based and may depend on order quantity, requested specification, packaging, destination, and current availability. Minimum order quantity and lead time should be confirmed for the requested order rather than assumed from a catalog listing or a previous purchase. For a meaningful comparison, specify the required quantity and delivery location when requesting prices. Also ask whether the quoted timeline begins after order confirmation, payment, or another agreed milestone.
For planning, distinguish between the time needed to confirm a specification, prepare an order, and transport it to the destination. Import requirements, shipping method, and document review may affect the overall schedule. If your project has a fixed date, communicate it early and ask the supplier to confirm a realistic delivery estimate. Avoid treating an indicative lead time as a guaranteed arrival date unless that commitment is explicitly agreed.
Maison Chemical supplies specialty chemicals and can discuss sourcing requirements for 2,4-Difluoro-3-methoxybenzoic acid CAS 178974-97-5. To help us assess your request, provide the target quantity, required assay or impurity limits, intended application category, destination, packaging preference, and desired delivery window. If your organization uses a specific specification template or analytical method, include it with the inquiry. We can then review the request and confirm the applicable product, documentation, price, and availability details.
2,4-Difluoro-3-methoxybenzoic acid CAS 178974-97-5 is identified by its aromatic acid structure, formula C8H6F2O3, and calculated molecular weight of approximately 188.13 g/mol. Those identifiers establish a useful starting point, but they do not define the assay, impurity profile, or commercial terms for a specific batch. The most reliable sourcing approach is to set application-based acceptance criteria, request batch-relevant documentation, and compare quotations on equal terms. Contact Maison Chemical with your quantity, specification, destination, and timing requirements to begin a product-specific sourcing discussion.
