Description

Application

• Forensic detection of N-Desmethylflunitrazepam: A method for detecting 92 analytes in oral fluid using LC-MS/MS, including N-Desmethylflunitrazepam, has been established, enhancing forensic toxicology practices (Desharnais et al., 2020).


• Quantitative analysis of benzodiazepine metabolites: Rapid determination of benzodiazepines and metabolites including N-Desmethylflunitrazepam in urine via direct injection LC-MS/MS, crucial for clinical and forensic investigations (Jeong et al., 2015).


• Optimizing chromatographic methods for benzodiazepines: Evaluation of high pH mobile phases in UHPLC-MS/MS for analyzing benzodiazepines and metabolites, such as N-Desmethylflunitrazepam, to improve detection in biological samples (Verplaetse et al., 2012).
