Chemical Structure
Description
CATO supplies 5-Methyl-12-oxo-N-(4-phenoxyphenyl)-5H,5aH,6H,7H,8H,9H,10H,12H-azepino[2,1-b]quinazoline-3-carboxamide (CAS 1775357-75-9), a certified reference material (molecular formula C27H27N3O3, MW 441.52 g/mol) for analytical method development and quality control.
Structurally, 5-Methyl-12-oxo-N-(4-phenoxyphenyl)-5H,5aH,6H,7H,8H,9H,10H,12H-azepino[2,1-b]quinazoline-3-carboxamide (C27H27N3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 441.52 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
