N-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)-2-((3-methyl-4-oxo-7-(p-tolyl)-3,4-dihydrothieno[3,2-d]pyrimidin-2-yl)thio)acetamide (CAS 1111292-29-5) is a high-purity analytical reference standard with the molecular formula C24H21N3O4S2 and a molecular weight of 479.57 g/mol.
Structurally, N-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)-2-((3-methyl-4-oxo-7-(p-tolyl)-3,4-dihydrothieno[3,2-d]pyrimidin-2-yl)thio)acetamide (C24H21N3O4S2) contains a flavonoid core, an amide group, a sulfone 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 479.57 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
