Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 4-(2-((3-methyl-4-oxo-7-(p-tolyl)-3,4-dihydrothieno[3,2-d]pyrimidin-2-yl)thio)acetamido)benzoate.

CATO supplies Ethyl 4-(2-((3-methyl-4-oxo-7-(p-tolyl)-3,4-dihydrothieno[3,2-d]pyrimidin-2-yl)thio)acetamido)benzoate (CAS 1040631-84-2), a certified reference material (molecular formula C25H23N3O4S2, MW 493.60 g/mol) for analytical method development and quality control.

Ethyl 4-(2-((3-methyl-4-oxo-7-(p-tolyl)-3,4-dihydrothieno[3,2-d]pyrimidin-2-yl)thio)acetamido)benzoate (C25H23N3O4S2) contains a flavonoid 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.

CATO manufactures Ethyl 4-(2-((3-methyl-4-oxo-7-(p-tolyl)-3,4-dihydrothieno[3,2-d]pyrimidin-2-yl)thio)acetamido)benzoate 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.
