6-ethyl-3-phenyl-2-sulfanyl-3H,4H-thieno[2,3-d]pyrimidin-4-one CAS 330449-38-2

Description

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.

6-ethyl-3-phenyl-2-sulfanyl-3H,4H-thieno[2,3-d]pyrimidin-4-one (CAS 330449-38-2) is a high-purity analytical reference standard with the molecular formula C14H24N2OS2 and a molecular weight of 300.48 g/mol.

Structurally, 6-ethyl-3-phenyl-2-sulfanyl-3H,4H-thieno[2,3-d]pyrimidin-4-one (C14H24N2OS2) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 300.48 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).
