Metabolite Identification
Common Nameo-Cresol
Descriptiono-Cresol is a minor urinary metabolite of toluene, O-cresol is a cresol that is phenol substituted by a methyl group at position 2. It is a minor urinary metabolite of toluene. It has a role as a human xenobiotic metabolite. It is widely used chemical with neurotoxicological properties (PMID:15687000 ). o-Cresol is used commercially as a disinfectant. Exposure may occur by inhalation, by cutaneous adsorption or by oral ingestion. o-Cresol denature and precipitate cellular proteins and thus may rapidly cause poisoning. o-Cresol is metabolized by conjugation and oxidation. Ingestion of o-Cresol cause intense burning of mouth and throat, followed by marked abdominal pain and distress. The minimum lethal dose of cresol by mouth is about 2 g (PMID 15040915 ). o-Cresol is a microbial metabolite that can be found in Pseudomonas. Besides, o-Cresol is one of the chemical compounds found in castoreum. This compound is gathered from the beaver's castor glands and found in the white cedar consumed by the beavers. Together with many other compounds, o-cresol is traditionally extracted from coal tar, the volatile materials obtained in the production of coke from coal. A similar source material is petroleum residues. These residue contains a few percent by weight of phenol and isomeric cresols. In addition to the materials derived from these natural sources, about two thirds of the Western world's supply is produced by methylation of phenol using methanol.
