Chemical Structure

2,5-Dibromothiophene CAS 3141-27-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 241.93 g/mol gives 2,5-Dibromothiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2,5-Dibromothiophene (CAS 3141-27-3), a certified reference material (molecular formula C4H2Br2S, MW 241.93 g/mol) for analytical method development and quality control.

Based on its molecular formula C4H2Br2S, 2,5-Dibromothiophene contains sulfur-containing functionality, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 241.93 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 2,5-Dibromothiophene 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.
