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 4-((2-((2-Fluorophenyl)amino)-4-oxothiazol-5(4H)-ylidene)methyl)benzoic acid (CAS 494191-73-0), a certified reference material (molecular formula C17H11FN2O3S, MW 342.34 g/mol) for analytical method development and quality control.
4-((2-((2-Fluorophenyl)amino)-4-oxothiazol-5(4H)-ylidene)methyl)benzoic acid (C17H11FN2O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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 4-((2-((2-Fluorophenyl)amino)-4-oxothiazol-5(4H)-ylidene)methyl)benzoic acid 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.
