2-((3-Ethyl-4-oxo-7-phenyl-3,4-dihydrothieno[3,2-d]pyrimidin-2-yl)thio)-N-(3-methoxybenzyl)acetamide (CAS 1040635-41-3) is a high-purity analytical reference standard with the molecular formula C24H23N3O3S2 and a molecular weight of 465.59 g/mol.
Structurally, 2-((3-Ethyl-4-oxo-7-phenyl-3,4-dihydrothieno[3,2-d]pyrimidin-2-yl)thio)-N-(3-methoxybenzyl)acetamide (C24H23N3O3S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 465.59 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).
