Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 151.12 g/mol gives 4H-1,2,4-Triazole-3-sulfonyl fluoride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4H-1,2,4-Triazole-3-sulfonyl fluoride (CAS 78201-15-7), a certified reference material (molecular formula C2H2FN3O2S, MW 151.12 g/mol) for analytical method development and quality control.
4H-1,2,4-Triazole-3-sulfonyl fluoride (C2H2FN3O2S) contains an amide group, a sulfone group, a carboxylic acid 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4H-1,2,4-Triazole-3-sulfonyl fluoride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
