CATO supplies 3-(4-Isobutyl-5-oxo-4,5-dihydro-[1,2,4]triazolo[4,3-a]quinazolin-1-yl)-N-(4-methoxybenzyl)propanamide (CAS 902928-31-8), a certified reference material (molecular formula C24H27N5O3, MW 433.50 g/mol) for analytical method development and quality control.
The molecular framework of 3-(4-Isobutyl-5-oxo-4,5-dihydro-[1,2,4]triazolo[4,3-a]quinazolin-1-yl)-N-(4-methoxybenzyl)propanamide (C24H27N5O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
