Chemical Structure

3-Bromo-2-fluorothiophene CAS 71176-17-5 chemical structure

Description

CATO supplies 3-Bromo-2-fluorothiophene (CAS 71176-17-5), a certified reference material (molecular formula C4H2BrFS, MW 181.03 g/mol) for analytical method development and quality control.

Owing to sulfur-containing functionality, fluorine/bromine substitution, 3-Bromo-2-fluorothiophene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 181.03 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.

CATO manufactures 3-Bromo-2-fluorothiophene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
