Description
CATO supplies N-(3,5-Dimethylphenyl)-5-ethyl-11-oxo-5H,5aH,6H,7H,8H,9H,11H-pyrido[2,1-b]quinazoline-3-carboxamide (CAS 1574582-36-7), a certified reference material (molecular formula C23H27N3O2, MW 377.48 g/mol) for analytical method development and quality control.
Structurally, N-(3,5-Dimethylphenyl)-5-ethyl-11-oxo-5H,5aH,6H,7H,8H,9H,11H-pyrido[2,1-b]quinazoline-3-carboxamide (C23H27N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 377.48 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.
