Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4-Aminophenyl)(2-methyl-4,5-dihydrobenzo[b]imidazo[4,5-d]azepin-6(1H)-yl)methanone.
CATO supplies (4-Aminophenyl)(2-methyl-4,5-dihydrobenzo[b]imidazo[4,5-d]azepin-6(1H)-yl)methanone (CAS 195531-22-7), a certified reference material (molecular formula C19H18N4O, MW 318.37 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (4-Aminophenyl)(2-methyl-4,5-dihydrobenzo[b]imidazo[4,5-d]azepin-6(1H)-yl)methanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 318.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
