Chemical Structure
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.
8-((3,5-Dimethylpiperidin-1-yl)sulfonyl)benzo[4,5]thieno[3,2-d]pyrimidin-4(3H)-one (CAS 440627-35-0), molecular formula C17H19N3O3S2 and molecular weight 377.48 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 8-((3,5-Dimethylpiperidin-1-yl)sulfonyl)benzo[4,5]thieno[3,2-d]pyrimidin-4(3H)-one (C17H19N3O3S2) 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 10.0, corresponding to approximately 10 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.
