5-Bromo-4-(chlorosulfonyl)thiophene-2-carboxylic acid CAS 172461-89-1

Description

Compared with other compounds in its class, the molecular weight of 305.55 g/mol gives 5-Bromo-4-(chlorosulfonyl)thiophene-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 5-Bromo-4-(chlorosulfonyl)thiophene-2-carboxylic acid (CAS 172461-89-1), a certified reference material (molecular formula C5H2BrClO4S2, MW 305.55 g/mol) for analytical method development and quality control.

Owing to a carbohydrate-derived structure, a sulfone group, chlorine/bromine substitution, 5-Bromo-4-(chlorosulfonyl)thiophene-2-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 305.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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-Bromo-4-(chlorosulfonyl)thiophene-2-carboxylic acid 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.
