4-Chloro-N-[5-(trifluoromethyl)-1,3,4-thiadiazol-2-yl]benzene-1-sulfonamide CAS 339103-74-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Chloro-N-[5-(trifluoromethyl)-1,3,4-thiadiazol-2-yl]benzene-1-sulfonamide.

4-Chloro-N-[5-(trifluoromethyl)-1,3,4-thiadiazol-2-yl]benzene-1-sulfonamide (CAS 339103-74-1), molecular formula C9H5ClF3N3O2S2 and molecular weight 343.73 g/mol, is a CATO reference standard with documented purity and traceability.

4-Chloro-N-[5-(trifluoromethyl)-1,3,4-thiadiazol-2-yl]benzene-1-sulfonamide (C9H5ClF3N3O2S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 4-Chloro-N-[5-(trifluoromethyl)-1,3,4-thiadiazol-2-yl]benzene-1-sulfonamide 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.
