Chemical Structure
Description
The occurrence of 2-{4-oxo-7-phenyl-3H,4H-thieno[3,2-d]pyrimidin-3-yl}-N-(3-phenylpropyl)acetamide is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-{4-oxo-7-phenyl-3H,4H-thieno[3,2-d]pyrimidin-3-yl}-N-(3-phenylpropyl)acetamide (CAS 1105206-84-5), a certified reference material (molecular formula C23H21N3O2S, MW 403.50 g/mol) for analytical method development and quality control.
The molecular framework of 2-{4-oxo-7-phenyl-3H,4H-thieno[3,2-d]pyrimidin-3-yl}-N-(3-phenylpropyl)acetamide (C23H21N3O2S) 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 2-{4-oxo-7-phenyl-3H,4H-thieno[3,2-d]pyrimidin-3-yl}-N-(3-phenylpropyl)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.
