2-({3-ethyl-4-oxo-7-phenyl-3H,4H-thieno[3,2-d]pyrimidin-2-yl}sulfanyl)-N-(2,4,6-trimethylphenyl)acetamide CAS 1040660-23-8 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 2-({3-ethyl-4-oxo-7-phenyl-3H,4H-thieno[3,2-d]pyrimidin-2-yl}sulfanyl)-N-(2,4,6-trimethylphenyl)acetamide.

2-({3-ethyl-4-oxo-7-phenyl-3H,4H-thieno[3,2-d]pyrimidin-2-yl}sulfanyl)-N-(2,4,6-trimethylphenyl)acetamide (CAS 1040660-23-8) is a high-purity analytical reference standard with the molecular formula C25H25N3O2S2 and a molecular weight of 463.61 g/mol.

2-({3-ethyl-4-oxo-7-phenyl-3H,4H-thieno[3,2-d]pyrimidin-2-yl}sulfanyl)-N-(2,4,6-trimethylphenyl)acetamide (C25H25N3O2S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), 2-({3-ethyl-4-oxo-7-phenyl-3H,4H-thieno[3,2-d]pyrimidin-2-yl}sulfanyl)-N-(2,4,6-trimethylphenyl)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.
