Norfludiazepam is a psychoactive drug and a metabolite of the benzodiazepine flunitrazepam. It belongs to the class of sedative-hypnotic compounds and exhibits anxiolytic, sedative, and muscle relaxant properties. Due to its structural similarity to other benzodiazepines, norfludiazepam is of interest in pharmacological research and forensic toxicology, particularly in the context of drug metabolism and toxicological analysis.
