Methylhippuric acid is a
carboxylic acid and organic compound. Methylhippuric acid has three isomers. The isomers include 2-, 3-, and 4-methylhippuric acid.[1]
Methylhippuric acids are metabolites of the isomers of
xylene.[1][2] The presence of methylhippuric acid can be used as a
biomarker to determine exposure to xylene.[2][3]
