5-(4-Bromobenzenesulfonyl)-4-methyl-1,2,3-thiadiazole CAS 338978-76-0

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution, 5-(4-Bromobenzenesulfonyl)-4-methyl-1,2,3-thiadiazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 319.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

5-(4-Bromobenzenesulfonyl)-4-methyl-1,2,3-thiadiazole (CAS 338978-76-0), molecular formula C9H7BrN2O2S2 and molecular weight 319.20 g/mol, is a CATO reference standard with documented purity and traceability.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
