5,7-Dichloro-N-(m-tolyl)thiazolo[4,5-d]pyrimidine-2-sulfonamide CAS 1000575-59-6

Description

5,7-Dichloro-N-(m-tolyl)thiazolo[4,5-d]pyrimidine-2-sulfonamide (C12H8Cl2N4O2S2) 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).

5,7-Dichloro-N-(m-tolyl)thiazolo[4,5-d]pyrimidine-2-sulfonamide (CAS 1000575-59-6), molecular formula C12H8Cl2N4O2S2 and molecular weight 375.25 g/mol, is a CATO reference standard with documented purity and traceability.
