Chemical Structure
Description
As a certified reference material (CRM), 3-Bromo-2-(difluoromethyl)thiophene 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.
CATO supplies 3-Bromo-2-(difluoromethyl)thiophene (CAS 1403667-53-7), a certified reference material (molecular formula C5H3BrF2S, MW 213.04 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, fluorine/bromine substitution, 3-Bromo-2-(difluoromethyl)thiophene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 213.04 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.
