Description

General description

This stable-labeled internal standard is suitable for quantitation of α-hydroxyalprazolam levels in urine, serum, or plasma by LC/MS or GC/MS for urine drug testing, clinical toxicology, forensic analysis, or isotope dilution methods. α-Hydroxyalprazolam is a major urinary metabolite of alprazolam, a benzodiazepine drug approved to treat panic and other anxiety disorders including generalized or social anxiety disorder.

Application

• alpha-Hydroxyalprazolam-d₅ as a mass spectrometry standard: Utilized in GC-MS for confirming urinary benzodiazepine metabolites, alpha-Hydroxyalprazolam-d₅ serves as a precise internal standard, enhancing the reliability of analytical measurements in toxicological studies (Meatherall, 1994).


• Application in benzodiazepine metabolite research: alpha-Hydroxyalprazolam-d₅ is employed in the GC/MS analysis of common benzodiazepine metabolites, specifically as a stable isotope-labeled compound for improved accuracy in quantitative toxological analysis (West and Ritz, 1993).
