Description
N-(3-Chloro-4-methoxyphenyl)-2-{[3-methyl-7-(4-methylphenyl)-4-oxo-3H,4H-thieno[3,2-d]pyrimidin-2-yl]sulfanyl}acetamide (CAS 1111265-59-8), molecular formula C23H20ClN3O3S2 and molecular weight 486.01 g/mol, is a CATO reference standard with documented purity and traceability.
N-(3-Chloro-4-methoxyphenyl)-2-{[3-methyl-7-(4-methylphenyl)-4-oxo-3H,4H-thieno[3,2-d]pyrimidin-2-yl]sulfanyl}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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures N-(3-Chloro-4-methoxyphenyl)-2-{[3-methyl-7-(4-methylphenyl)-4-oxo-3H,4H-thieno[3,2-d]pyrimidin-2-yl]sulfanyl}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.
