p‑Methylbenzoic Acid is an aromatic carboxylic acid featuring a para‑methyl substituted benzene ring, which provides defined steric and electronic characteristics in organic synthesis. Identified by CAS 99‑94‑5 and also known as p‑toluic acid, it is typically supplied as a crystalline solid with stable chemical behavior under standard conditions. These properties support its common use as a chemical intermediate in industrial synthesis systems where controlled aromatic functionality is required.
For industrial supply, this product is available with competitive factory pricing, supports customized specifications, and is provided with complete MSDS, TDS, COA documentation, with availability for bulk supply.

FAQ - Technical & Supply Chain
-
Q:
Is p‑Methylbenzoic Acid CAS 99‑94‑5 supplied as a solid or liquid?
A: It is supplied as a crystalline solid under normal conditions, which distinguishes it from liquid aromatic acids and affects storage and handling requirements. -
Q:
How does the para‑methyl position affect p‑Methylbenzoic Acid compared to other toluic acid isomers?
A: The para‑methyl substitution provides a more symmetrical molecular structure, which can influence melting point and reactivity patterns compared with ortho‑ or meta‑toluic acid isomers.
