  • Applications

    Nordiazepam (CAS 1088-11-5) is a benzodiazepine-related compound primarily used as an intermediate or synthetic precursor in the manufacture of other benzodiazepines (such as diazepam) and as an active metabolite with a longer half-life. It is also used as an analytical reference standard for drug and toxicology testing (LC-MS/GC-MS) to identify and quantify benzodiazepines. In pharmacology and pharmacokinetic research, Nordiazepam is employed to study metabolic properties and biological effects of benzodiazepines. It also serves as a standard for impurity profiling and quality control in pharmaceutical development, subject to local regulations and formulation limits.
