Description
2-((3-Ethyl-4-oxo-7-(p-tolyl)-3,4-dihydrothieno[3,2-d]pyrimidin-2-yl)thio)-N-(3-fluoro-4-methylphenyl)acetamide (CAS 1040632-60-7), molecular formula C24H22FN3O2S2 and molecular weight 467.58 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-((3-Ethyl-4-oxo-7-(p-tolyl)-3,4-dihydrothieno[3,2-d]pyrimidin-2-yl)thio)-N-(3-fluoro-4-methylphenyl)acetamide (C24H22FN3O2S2) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. 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 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).
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-((3-Ethyl-4-oxo-7-(p-tolyl)-3,4-dihydrothieno[3,2-d]pyrimidin-2-yl)thio)-N-(3-fluoro-4-methylphenyl)acetamide 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.
