2-(1,2,3-Thiadiazol-4-yl)phenyl 4-chlorobenzene-1-sulfonate CAS 303148-76-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(1,2,3-Thiadiazol-4-yl)phenyl 4-chlorobenzene-1-sulfonate.

2-(1,2,3-Thiadiazol-4-yl)phenyl 4-chlorobenzene-1-sulfonate (CAS 303148-76-7), molecular formula C14H9ClN2O3S2 and molecular weight 352.82 g/mol, is a CATO reference standard with documented purity and traceability.

2-(1,2,3-Thiadiazol-4-yl)phenyl 4-chlorobenzene-1-sulfonate (C14H9ClN2O3S2) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 2-(1,2,3-Thiadiazol-4-yl)phenyl 4-chlorobenzene-1-sulfonate 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.
