Description
2-((3-(4-Methoxyphenyl)-4-oxo-3,4,5,6,7,8-hexahydrobenzo[4,5]thieno[2,3-d]pyrimidin-2-yl)thio)-N-(m-tolyl)acetamide (CAS 477330-41-9), molecular formula C26H25N3O3S2 and molecular weight 491.63 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-((3-(4-Methoxyphenyl)-4-oxo-3,4,5,6,7,8-hexahydrobenzo[4,5]thieno[2,3-d]pyrimidin-2-yl)thio)-N-(m-tolyl)acetamide (C26H25N3O3S2) 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.
