    Oxazepam-d5 (CRM) is a certified reference material that is structurally categorized as a benzodiazepine. Oxazepam-d5 (CRM) is intended for use as an internal standard for the quantification of oxazepam (Item No. ISO60173) by GC- or LC-mass spectrometry. Oxazepam is an active metabolite of diazepam (Item No. ISO60177), prazepam, and temazepam (Item No. ISO60182) that can positively modulate GABAA receptors, which results in inhibitory effects in the central nervous system.1 This product is intended for forensic and research purposes.
