Descripción

General description

Pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards

Application

• Pharmacokinetic Study of Alpha-Hydroxytriazolam: Research involving the urinary excretion of alpha-hydroxytriazolam after a single dose of Halcion provides insights into the metabolic pathways and elimination characteristics of this benzodiazepine derivative. Using α-Hydroxytriazolam-d₄ as an internal standard in mass spectrometry enhances the accuracy of such studies, which is critical for understanding the drug′s behavior in the human body and for developing therapeutic guidelines (Lin et al., 2005).


• Confirmation of Urinary Benzodiazepine Metabolites: A study that utilizes gas chromatography-mass spectrometry (GC-MS) to confirm the presence of urinary benzodiazepine metabolites, including α-Hydroxytriazolam, emphasizes the role of α-Hydroxytriazolam-d₄ as a vital analytical standard. This research aids in forensic toxicology and clinical diagnostics by providing robust methodologies for the detection and quantification of benzodiazepines in biological samples (Meatherall, 1994).

Analysis Note
