2,4-Difluoro-3-methoxybenzoic acid is a fluorinated aromatic carboxylic acid identified by CAS 178974-97-5. I classify it primarily as a specialty pharmaceutical and fine-chemical intermediate rather than as a finished active pharmaceutical ingredient. Its molecular structure combines a benzoic acid group with two fluorine substituents and one methoxy group, giving it a molecular formula of C8H6F2O3 and a calculated molecular weight of approximately 188.13 g/mol. Buyers should confirm identity, assay, impurity profile, packaging, and intended-use documentation before placing a commercial order.
2,4-Difluoro-3-methoxybenzoic acid is an aromatic carboxylic acid containing a benzene ring substituted at defined positions. The carboxylic acid group provides a reactive handle for subsequent synthetic steps, while the fluorine and methoxy substituents modify the electronic and steric character of the aromatic ring. These structural features make the compound useful for route development where controlled substitution patterns are important.
In practical procurement, the CAS number is the first identity check, but it should not be the only one. I recommend comparing the CAS number, chemical name, molecular formula, molecular weight, structural representation, and analytical data on the supplier’s certificate of analysis. This approach helps reduce the risk of confusing the material with another difluorinated or methoxylated benzoic acid derivative.

The main function of this compound is to serve as a building block in organic synthesis. Its carboxylic acid group can participate in transformations such as amidation, esterification, and other medicinal-chemistry route steps when compatible reagents and conditions are selected. The fluorine atoms can influence molecular polarity, acidity, lipophilicity, and metabolic behavior in downstream molecules, although the effect depends on the complete final structure.
I would not describe this material as a universal ingredient or as a finished pharmaceutical product. Its value depends on the reaction route, the required impurity limits, and the performance of the downstream process. In research and development, it may be evaluated for the preparation of substituted benzamides, esters, heterocycle-linked intermediates, or other aromatic compounds, but the exact use must be confirmed by the customer’s synthetic design.
These applications are route-dependent rather than guaranteed product outcomes. Before procurement, I recommend sharing the planned reaction type, target batch size, required assay, and any restricted impurity list with the supplier. That information allows the supplier to assess whether the available grade is appropriate for laboratory, pilot, or commercial development.
As an aromatic carboxylic acid, 2,4-difluoro-3-methoxybenzoic acid should be handled as a specialty organic solid according to the supplier’s safety documentation and confirmed physical data. However, appearance, melting behavior, water content, residual solvents, and particle characteristics can vary with manufacturing and crystallization conditions. I therefore recommend treating supplier-specific specifications as controlling rather than relying only on general database descriptions.

For B2B purchasing, the most useful material options are usually defined by analytical requirements rather than by different commercial “types.” A research-grade lot may be suitable for early screening, while a process-development grade may require tighter control of related substances, residual solvents, water, and batch-to-batch consistency. If the material will enter a regulated development program, the documentation package becomes as important as the nominal assay.
I recommend evaluating this product through a technical and commercial checklist rather than choosing solely on price. First, confirm that the supplier can provide the exact CAS number and a recent batch-specific certificate of analysis. Next, compare assay methodology, impurity reporting, packaging, lead time, and the supplier’s ability to support repeat orders.
Price should be assessed together with total procurement risk. A lower quoted price may not be advantageous if the lot requires additional purification, lacks suitable analytical data, or cannot be replenished within the project schedule. For a development program, I suggest asking for a sample or representative batch data before approving a larger purchase, subject to the supplier’s sampling policy.
At Maison Chemical, we support B2B buyers evaluating 2,4-difluoro-3-methoxybenzoic acid CAS 178974-97-5 as a pharmaceutical or fine-chemical intermediate. We can discuss intended application, required quantity, assay expectations, packaging, documentation, and delivery planning before quotation. Our role is to help customers determine whether the available material specification aligns with their route and quality requirements.
For customers moving from laboratory research to process development, we recommend defining acceptance criteria early. These criteria may include minimum assay, related-substance limits, water content, residual solvents, packaging configuration, and a required delivery window such as 2–8 weeks, depending on stock status and production planning. Any quoted lead time, quantity, and specification should be confirmed for the individual order rather than assumed from a general product listing.
2,4-Difluoro-3-methoxybenzoic acid CAS 178974-97-5 is a defined fluorinated building block that may be suitable when your synthetic route requires its specific substitution pattern and carboxylic acid functionality. It should be evaluated as an intermediate, not as a finished drug substance or a product with universal application. The most reliable buying decision comes from matching the supplier’s batch data and documentation to your reaction, quality, and delivery requirements.
As a next step, prepare your target quantity, required purity, impurity limits, packaging preference, destination, and intended application. Send these details to Maison Chemical for a technical and commercial review of availability, documentation, and supply options. We can then help you determine whether the material is appropriate for your current laboratory, process-development, or repeat procurement needs.
