CATO supplies 2-[4-(8-Bromo-3-methyl-2-oxo-2,3-dihydroimidazo[4,5-c]quinolin-1-yl)phenyl]-2-methylpropionitrile (CAS 915019-50-0), a certified reference material (molecular formula C21H17BrN4O, MW 421.29 g/mol) for analytical method development and quality control.
The molecular framework of 2-[4-(8-Bromo-3-methyl-2-oxo-2,3-dihydroimidazo[4,5-c]quinolin-1-yl)phenyl]-2-methylpropionitrile (C21H17BrN4O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
