General description

Desalkylflurazepam, also known as N-desalkyl-2-oxoquazepam, is a long-acting metabolite of the benzodiazepine drug flurazepam. Flurazepam is sold unde the trade names Dalmane and Dalmadorm for the treatment of mild to moderate insomnia. This Certified Spiking Solution® is suited for use in LC/MS or GC/MS applications for clinical toxicology, forensic analysis or urine drug testing.

Application


  • Pharmacokinetic profiling: Research on flurazepam metabolites, including Desalkylflurazepam, utilizes high-performance liquid chromatography for detailed pharmacokinetic studies in rats, providing essential data for understanding drug behavior and metabolism (Lau et al., 1987).

  • Neuroscience tool: Desalkylflurazepam is applied in neuroscience research to understand the dynamics of benzodiazepine binding on living cells, utilizing small ligands in fluorescence correlation spectroscopy, a method pivotal for real-time molecular interactions study (Hegener et al., 2002).

  • Drug testing applications: The compound is used in the development of analytical techniques like ultra-high-performance liquid chromatography-mass spectrometry (UHPLC-MS/MS) for the detection of benzodiazepines in hair, useful in workplace drug testing and forensic science (Ramírez Fernández et al., 2015).

  • Toxicological analysis: Desalkylflurazepam serves as a reference standard in forensic toxicology to facilitate the rapid determination of benzodiazepines and their metabolites in biological samples, crucial for accurate and swift diagnostic purposes (Jeong et al., 2015).

  • Immunosorbent assay applications: This benzodiazepine metabolite is instrumental in examining cross-reactivity of psychoactive substances in enzyme-linked immunosorbent assay (ELISA) techniques, enhancing drug testing capabilities in clinical settings (Cieri et al., 2024).
