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 6-Chloro-3-(4-chlorobenzenesulfonyl)-2H-chromen-2-one (CAS 866013-21-0), a certified reference material (molecular formula C15H8Cl2O4S, MW 355.19 g/mol) for analytical method development and quality control.
6-Chloro-3-(4-chlorobenzenesulfonyl)-2H-chromen-2-one (C15H8Cl2O4S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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 6-Chloro-3-(4-chlorobenzenesulfonyl)-2H-chromen-2-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.
