Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies N-(3-chloro-4-methoxyphenyl)-2-((3-ethyl-4-oxo-7-phenyl-3,4-dihydrothieno[3,2-d]pyrimidin-2-yl)thio)acetamide (CAS 1040662-69-8), a certified reference material (molecular formula C23H20ClN3O3S2, MW 486.01 g/mol) for analytical method development and quality control.
N-(3-chloro-4-methoxyphenyl)-2-((3-ethyl-4-oxo-7-phenyl-3,4-dihydrothieno[3,2-d]pyrimidin-2-yl)thio)acetamide (C23H20ClN3O3S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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).
CATO manufactures N-(3-chloro-4-methoxyphenyl)-2-((3-ethyl-4-oxo-7-phenyl-3,4-dihydrothieno[3,2-d]pyrimidin-2-yl)thio)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.
