5-Methylsalicylic acid Chemical Properties,Uses,Production

Chemical Properties

5-Methylsalicylic acid is a white to beige powder 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.


Toxicity is similar to salicylic acid. 5-Methylsalicylic acid is used in manufacturing of dyes.


5-Methylsalicylic acid was used in generation of o-sulfate conjugates in situ and their analysis by ultra-performance liquid chromatography-time-of-flight mass spectrometry.


5-Methylsalicylic acid can be prepared by hydroxylation of 3-methylbenzoic acid.

General Description

5-Methylsalicylic acid exhibits a significant cross-reactivity during fluorescent polarization immunoassay for salicylates in serum.

Purification Methods

Crystallise the acid from H2O. [Beilstein 10 H 227, 10 II 134, 10 III 516, 10 IV 610.]
