5-((4-Bromobenzyl)sulfonyl)-3-chloro-1,2,4-thiadiazole CAS 494763-24-5

Description

The occurrence of 5-((4-Bromobenzyl)sulfonyl)-3-chloro-1,2,4-thiadiazole is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-((4-Bromobenzyl)sulfonyl)-3-chloro-1,2,4-thiadiazole (CAS 494763-24-5), molecular formula C9H6BrClN2O2S2 and molecular weight 353.64 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, 5-((4-Bromobenzyl)sulfonyl)-3-chloro-1,2,4-thiadiazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 353.64 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).

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), 5-((4-Bromobenzyl)sulfonyl)-3-chloro-1,2,4-thiadiazole 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.
