N-(2,4-Dimethylphenyl)-2-{4-oxo-7-phenyl-3H,4H-thieno[3,2-d]pyrimidin-3-yl}acetamide CAS 1105223-83-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(2,4-Dimethylphenyl)-2-{4-oxo-7-phenyl-3H,4H-thieno[3,2-d]pyrimidin-3-yl}acetamide.

N-(2,4-Dimethylphenyl)-2-{4-oxo-7-phenyl-3H,4H-thieno[3,2-d]pyrimidin-3-yl}acetamide (CAS 1105223-83-3), molecular formula C22H19N3O2S and molecular weight 389.47 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-(2,4-Dimethylphenyl)-2-{4-oxo-7-phenyl-3H,4H-thieno[3,2-d]pyrimidin-3-yl}acetamide (C22H19N3O2S) 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).

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 N-(2,4-Dimethylphenyl)-2-{4-oxo-7-phenyl-3H,4H-thieno[3,2-d]pyrimidin-3-yl}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.
