HPLC Method for Determination of Triazolam on Newcrom R1 Column
High Performance Liquid Chromatography (HPLC) Method for Analysis of Triazolam .
Triazolam is a prescription-strength benzodiazepine with the chemical formula C17H12Cl2N4 . It is used to treat insomnia, as it is a central nervous system depressant tranquilizer. Compared to other benzodiazepines, it is fairly obscure, preventing misuse and abuse of it. It is a Schedule IV drug.
Triazolam can be retained and analyzed on a Newcrom R1 reverse-phase column using a simple isocratic analytical method with a mobile phase consisting of Acetonitrile (MeCN), water, and Sulfuric acid as the ionic modifier. This analysis method can be UV detected at 200 nm with high resolution and peak symmetry.
