Orthotoluic

Orthotoluic is a chemical compound with the formula C8H8O2. It is one of three isomers of toluic acid, the others being metatoluic and paratoluic acid. The name "orthotoluic" indicates that the carboxyl group (-COOH) and the methyl group (-CH3) are attached to adjacent carbon atoms on the benzene ring. It is also known by its IUPAC name, 2-methylbenzoic acid.

This organic acid is a white crystalline solid at room temperature. It is sparingly soluble in water but dissolves readily in organic solvents such as ethanol and ether. Orthotoluic acid can be synthesized through various methods, including the oxidation of o-xylene. It is used as an intermediate in the production of other chemicals, including dyes, pharmaceuticals, and agricultural products. Its specific applications often depend on its reactivity as a carboxylic acid and the presence of the methyl group on the aromatic ring.
