CATO supplies 2-(piperidin-1-ylmethyl)-5-(thiophen-2-yl)-3H,4H-thieno[2,3-d]pyrimidin-4-one (CAS 255378-91-7), a certified reference material (molecular formula C16H17N3OS2, MW 331.46 g/mol) for analytical method development and quality control.
Structurally, 2-(piperidin-1-ylmethyl)-5-(thiophen-2-yl)-3H,4H-thieno[2,3-d]pyrimidin-4-one (C16H17N3OS2) 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 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 331.46 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).
CATO manufactures 2-(piperidin-1-ylmethyl)-5-(thiophen-2-yl)-3H,4H-thieno[2,3-d]pyrimidin-4-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
