General description

Hippuric acid, the glycine conjugate of benzoic acid, is formed via a biotransformation process.[1] From scientific literature, it is reported to be found as an excretory product in urine. Hippuric acid is also known to be catabolically synthesized from benzene-type aromatic compounds, believed to be originated from various factors such as environmental exposures, basic human liver metabolism of protein catabolism, cyclic sugar type-compounds, quinic acid, etc.[2]

Application

Hippuric acid may be used as an analytical reference standard for the quantification of the analyte in the following:
  • Human biological fluids using high-performance liquid chromatography (HPLC) with UV detection.[1]
  • Human and rat urine samples using gas chromatography–mass spectrometry (GC–MS).[3]
  • Human urine samples using GC equipped with a flame ionization detector.[4]
