p-Toluic Acid · CAS 99-94-5
4-Methylbenzoic acid (p-toluic acid) is a white to off-white crystalline powder — the para isomer of the three toluic acids, widely used as an intermediate in pharmaceuticals, agrochemicals, dyes and photosensitive materials. Melting point 179-182 °C; poorly soluble in cold water, soluble in ethanol, ether and other organic solvents.
The para carboxyl group enjoys low steric hindrance and high reactivity, suitable for rapid acylation, esterification and cyanation with efficient downstream conversion, meeting both pharmaceutical-grade and industrial-grade standards.
