Metabolite Identification
Common NameNordiazepam
DescriptionNordiazepam, also known as desmethyldiazepam or dealkylprazepam, belongs to the class of organic compounds known as 1,4-benzodiazepines. These are organic compounds containing a benzene ring fused to a 1,4-azepine. Nordiazepam is a moderately basic compound (based on its pKa). Outside of the human body, nordiazepam has been detected, but not quantified in, a few different foods, such as common wheats, corns, and potato. This could make nordiazepam a potential biomarker for the consumption of these foods. A 1,4-benzodiazepinone having phenyl and chloro substituents at positions 5 and 7 respectively; it has anticonvulsant, anxiolytic, muscle relaxant and sedative properties but is used primarily in the treatment of anxiety. Nordiazepam is a potentially toxic compound.
