N-(4-Chloro-3-ethyl-5-formylthiazol-2(3H)-ylidene)benzenesulfonamide (CAS 627471-09-4), molecular formula C12H11ClN2O3S2 and molecular weight 330.81 g/mol, is a CATO reference standard with documented purity and traceability.
N-(4-Chloro-3-ethyl-5-formylthiazol-2(3H)-ylidene)benzenesulfonamide (C12H11ClN2O3S2) contains a nitrogen-containing heterocyclic scaffold, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
