General description

Oxazepam glucuronide is a major urinary metabolite of the benzodiazepine drug, oxazepam. Oxazepam, marketed as Alepam, Medopam, or Murelax®, has been used extensively since the 1960s for treatment of anxiety and insomnia and in the control of symptoms of alcohol withdrawal. This certified reference solution is suitable for GC/MS or LC/MS applications with oxazepam or oxazepam glucuronide such as urine drug testing, pain prescription monitoring, toxicology analysis, or forensic testing.

Application


  • Advanced Analytical Techniques for Benzodiazepine Metabolites: Oxazepam glucuronide has been targeted in studies using high-performance liquid chromatography with tandem mass spectrometry (HPLC-MS/MS). This method allows for the sensitive and automatic determination of diazepam and its metabolites, including oxazepam glucuronide, in human oral fluid, highlighting its utility in forensic and clinical toxicology (Jiang et al., 2016).

  • Forensic Applications: Oxazepam glucuronide is directly determined using μElution solid-phase extraction and liquid chromatography-tandem mass spectrometry (LC-MS/MS) in human whole blood. This technique is crucial for forensic science, providing reliable data for legal and medical investigations involving benzodiazepine use (Wang et al., 2013).
