Description
CATO supplies 5-((3-Chloro-4-methoxyphenyl)sulfonyl)-2-thioxo-2,3-dihydropyrimidin-4(1H)-one (CAS 931938-36-2), a certified reference material (molecular formula C11H9ClN2O4S2, MW 332.78 g/mol) for analytical method development and quality control.
The molecular framework of 5-((3-Chloro-4-methoxyphenyl)sulfonyl)-2-thioxo-2,3-dihydropyrimidin-4(1H)-one (C11H9ClN2O4S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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).
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 5-((3-Chloro-4-methoxyphenyl)sulfonyl)-2-thioxo-2,3-dihydropyrimidin-4(1H)-one 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.
