m-toluic acid

m-Toluic acid (CAS 99-04-7), also known as 3-MBA, is an aromatic carboxylic acid used as a building block and functional intermediate across pharmaceutical synthesis, specialty coatings, and preservation applications.

Its reactivity as an acid intermediate makes it a reliable starting material where controlled esterification or salt formation is required. In pharmaceutical manufacturing, 3-MBA serves as a key intermediate in synthesis.

This is particularly useful where a substituted benzoic acid scaffold is required. Coatings and resin formulators use it as a catalyst precursor or crosslinking component to influence cure rates and film performance.

In preservation systems, it functions as a biocidal agent in industrial formulations where microbial control is needed without relying on halogenated compounds. This ensures safety and efficacy in various systems.

Personal care chemists incorporate it into select formulations as an antioxidant stabilizer to extend product shelf life. This versatility makes it a staple for formulators looking for reliable chemical stability.

m-Toluic acid is supplied as a white to off-white crystalline powder. Standard commercial grades include technical and pharmaceutical-grade material, with pharma-grade product typically meeting USP or BP specifications.

Bulk quantities are available for industrial procurement alongside smaller quantities for R&D and formulation development. This ensures that both large scale manufacturers and research labs have access to the material.
