CATO supplies (R)-1-(4-Bromophenyl)-7,8-dimethoxy-N,4-dimethyl-4,5-dihydro-3H-benzo[d][1,2]diazepine-3-carboxamide (CAS 1564271-34-6), a certified reference material (molecular formula C20H22BrN3O3, MW 432.31 g/mol) for analytical method development and quality control.
(R)-1-(4-Bromophenyl)-7,8-dimethoxy-N,4-dimethyl-4,5-dihydro-3H-benzo[d][1,2]diazepine-3-carboxamide (C20H22BrN3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
