4-Methylbenzoic Acid — CAS 99-94-5
4-Methylbenzoic Acid — CAS 99-94-5
4-Methylbenzoic acid (p-toluic acid, CAS 99-94-5) is an aromatic carboxylic acid and a versatile chemical intermediate across pharmaceutical, polymer, dye, and specialty chemical synthesis sectors. UAB An Group Export supplies it in technical and synthesis grades, matched to each customer's process and application requirements.
It is used primarily as a synthesis building block and oxidation precursor in pharmaceutical intermediate production, polyester and polymer manufacturing, dye synthesis, and specialty chemical applications. Its methyl group provides a handle for further oxidative functionalization to terephthalic acid derivatives, while its carboxylic acid group enables esterification, amidation, and condensation reactions across a wide range of downstream synthesis pathways.
For qualified industrial buyers, supply is coordinated around grade, purity, volume, packaging, and delivery destination, in line with applicable product and handling regulations. Bulk and commercial orders are both handled — send your requirements and we'll prepare a quote covering supply, packaging, logistics, and delivery.
Key Applications
Pharmaceutical Intermediate SynthesisUsed as a building block in pharmaceutical synthesis requiring a para-methylbenzoic acid scaffold — the methyl group can be selectively oxidized to a second carboxylic acid group to give terephthalic acid derivatives, or functionalized through halogenation and other transformations for a range of pharmaceutical intermediate constructions.
Polyester & Polymer ManufacturingUsed as a monomer and chain terminator in select polyester and specialty polymer synthesis applications, and as an oxidation precursor in terephthalic acid derivative production.
Dye & Pigment ManufacturingUsed as an intermediate in the synthesis of select azo dyes and specialty colorants requiring a methylbenzoic acid scaffold.
Agrochemical ManufacturingUsed as a building block in the synthesis of select herbicides and agrochemical active ingredients requiring a para-substituted toluic acid intermediate.
Specialty Chemical SynthesisUsed across a range of organic synthesis applications requiring an aromatic carboxylic acid with a para-methyl substituent for selective oxidation, esterification, and functionalization reactions.
Supply & Packaging
Supplied according to your required grade and purity, quantity, packaging, and destination. 4-Methylbenzoic acid is a white crystalline solid at room temperature with a melting point of approximately 179–182°C and a faint aromatic odor. Packaging, transport, and handling are arranged according to applicable handling requirements, typically in sealed, moisture-proof bags or fiber drums.
Storage must be in sealed containers away from heat, strong oxidizing agents, and strong bases. Standard chemical handling PPE including gloves and eye protection is required during handling operations.
