Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, N-(3,5-Dimethylphenyl)-5-methyl-11-oxo-5H,5aH,6H,7H,8H,9H,11H-pyrido[2,1-b]quinazoline-3-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 363.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
