Application
3-Methylhippuric acid was employed as biological marker in studies on occupational exposure to xylene (solvent).
General description
3-Methylhippuric acid is also referred as m-methyl-hippuric acid. It is major product of xylene biotransformation in urine.

Solvent exposures commonly involve mixtures of substances or mixtures of isomers of a single solvent. These may be metabolised through common pathways, resulting in the potential for metabolic interactions. These may then lead to accumulation of solvent or metabolic intermediates

A high-performance liquid chromatographic method is described for the simultaneous determination of six urinary metabolites of several aromatic chemicals: phenol (from benzene), hippuric acid (from toluene), 3-methylhippuric acid (from xylene), mandelic and phenylglyoxylic acid (from styrene) and 4-nitrophenol (from nitrobenzene).

In a series of experiments to investigate interactions between industrial solvents and common medications the interaction between m-xylene and aspirin was studied. As both these substances are metabolised and excreted as glycine conjugates there would possibly be competition for this

The industrial solvents, toluene and xylene, have physicochemical properties that can be hazardous to the workers exposed. Since hippuric acid and m-methyl-hippuric acid represent the products of toluene and xylene biotransformation in urine, they are used as biological markers in
