2-Methyl Hippuric Acid is primarily used as a biomarker in occupational and environmental health studies. It is commonly monitored in urine samples to assess exposure to xylene, a solvent widely used in industrial settings such as paint, coatings, and chemical manufacturing. By measuring its levels, researchers and health professionals can evaluate the extent of xylene absorption in individuals, helping to ensure workplace safety and compliance with exposure limits. Additionally, it serves as a useful indicator in toxicology studies to understand the metabolic processing of xylene in the human body.
