It is a white solid that is soluble in basic water and in polar organic solvents. At neutral pH, the acid exists as 5-methylsalicylate Its functional groups include a carboxylic acid and a phenol group. It is one of four isomers of methylsalicylic acid. It can be prepared by hydroxylation of 3-methylbenzoic acid.[1] See also
