Metabolite Identification
Common Name(±)-2-Hydroxy-2-phenylacetonitrile
Description(±)-2-Hydroxy-2-phenylacetonitrile, also known as alpha-hydroxybenzeneacetonitrile or benzaldehyde cyanohydrin, 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. Cyanide is also known produce some of its toxic effects by binding to catalase, glutathione peroxidase, methemoglobin, hydroxocobalamin, phosphatase, tyrosinase, ascorbic acid oxidase, xanthine oxidase, succinic dehydrogenase, and Cu/Zn superoxide dismutase (±)-2-Hydroxy-2-phenylacetonitrile is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, (±)-2-Hydroxy-2-phenylacetonitrile has been detected, but not quantified in, fruits. This could make (±)-2-hydroxy-2-phenylacetonitrile a potential biomarker for the consumption of these foods. Mandelonitrile is a chemical compound of the cyanohydrin class (±)-2-Hydroxy-2-phenylacetonitrile is a potentially toxic compound. Consequently the primary mechanism of toxicity for organic nitriles is their production of toxic cyanide ions or hydrogen cyanide. Oxygen therapy can also be administered.
