Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(4-Benzylpiperidin-1-yl)-7-(3,4-diethoxyphenyl)-3H,4H-thieno[3,2-d]pyrimidin-4-one.
2-(4-Benzylpiperidin-1-yl)-7-(3,4-diethoxyphenyl)-3H,4H-thieno[3,2-d]pyrimidin-4-one (CAS 1242965-73-6) is a high-purity analytical reference standard with the molecular formula C28H31N3O3S and a molecular weight of 489.63 g/mol.
2-(4-Benzylpiperidin-1-yl)-7-(3,4-diethoxyphenyl)-3H,4H-thieno[3,2-d]pyrimidin-4-one (C28H31N3O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 2-(4-Benzylpiperidin-1-yl)-7-(3,4-diethoxyphenyl)-3H,4H-thieno[3,2-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.
