N1-(2-Hydroxyethyl) Flurazepam Hydrochloride (CAS 19011-77-9), molecular formula C17H14ClFN2O2 and molecular weight 332.76 g/mol, is a CATO reference standard with documented purity and traceability.
N1-(2-Hydroxyethyl) Flurazepam Hydrochloride (C17H14ClFN2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
