General description

o-Cresol is one of the key volatile phenolic components of wine, beechwood creosote and hardwood sawdust smoke. It is also a flavor component of red meat and aged Italian cheese.

Application


  • Ultrahigh-performance liquid chromatography-tandem mass spectrometry quantitation of o-cresol in hydrolyzed human urine to assess toluene exposure.: This paper presents a method for quantifying o-cresol in human urine using advanced chromatography techniques, emphasizing its application in assessing exposure to toluene and other related compounds (Langlois et al., 2023).
