N-[(3-Methoxyphenyl)methyl]-2-{4-oxo-7-phenyl-3H,4H-thieno[3,2-d]pyrimidin-3-yl}acetamide (CAS 1105234-91-0), molecular formula C22H19N3O3S and molecular weight 405.47 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-[(3-Methoxyphenyl)methyl]-2-{4-oxo-7-phenyl-3H,4H-thieno[3,2-d]pyrimidin-3-yl}acetamide (C22H19N3O3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-Methoxyphenyl)methyl]-2-{4-oxo-7-phenyl-3H,4H-thieno[3,2-d]pyrimidin-3-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.
