Metabolite Identification
Common NameIsothiocyanatobenzene
DescriptionPhenyl isothiocyanate, also known as benzene-1-isothiocyanate or phenyl mustard oil, belongs to the class of organic compounds known as benzene and substituted derivatives. These are aromatic compounds containing one monocyclic ring system consisting of benzene. Phenyl isothiocyanate is a chemical compound of cyanide. Exposure to high levels of cyanide for a short time harms the brain and heart and can even cause coma, seizures, apnea, cardiac arrest and death. Phenyl isothiocyanate is an extremely weak basic (essentially neutral) compound (based on its pKa). Phenyl isothiocyanate is a potentially toxic compound. The binding of cyanide to this cytochrome prevents transport of electrons from cytochrome c oxidase to oxygen. Cyanide binds to the ferric ion of methemoglobin to form inactive cyanmethemoglobin. SKIN: should be treated immediately by rinsing the affected parts in cold running water for at least 15 minutes, followed by thorough washing with soap and water. INHALATION: supply fresh air. This compound has been identified in human blood as reported by (PMID: 31557052 ). Isothiocyanatobenzene is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Isothiocyanatobenzene is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
