Chemical Structure

2-Bromo-4-chlorothiophene CAS 32431-92-8 chemical structure

Description

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.

CATO supplies 2-Bromo-4-chlorothiophene (CAS 32431-92-8), a certified reference material (molecular formula C4H2BrClS, MW 197.48 g/mol) for analytical method development and quality control.

Owing to sulfur-containing functionality, chlorine/bromine substitution, 2-Bromo-4-chlorothiophene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 197.48 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).

As a certified reference material (CRM), 2-Bromo-4-chlorothiophene 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.
