Description
CATO supplies N-(3-(methylthio)phenyl)-2-(4-oxo-7-phenylthieno[3,2-d]pyrimidin-3(4H)-yl)acetamide (CAS 1105235-84-4), a certified reference material (molecular formula C21H17N3O2S2, MW 407.51 g/mol) for analytical method development and quality control.
Structurally, N-(3-(methylthio)phenyl)-2-(4-oxo-7-phenylthieno[3,2-d]pyrimidin-3(4H)-yl)acetamide (C21H17N3O2S2) 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 407.51 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.
As a certified reference material (CRM), N-(3-(methylthio)phenyl)-2-(4-oxo-7-phenylthieno[3,2-d]pyrimidin-3(4H)-yl)acetamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
