3,5-Dibromothiophene-2-carboxylic acid CAS 7311-68-4

Description

The occurrence of 3,5-Dibromothiophene-2-carboxylic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3,5-Dibromothiophene-2-carboxylic acid (CAS 7311-68-4) is a high-purity analytical reference standard with the molecular formula C5H2Br2O2S and a molecular weight of 285.94 g/mol.

Based on its molecular formula C5H2Br2O2S, 3,5-Dibromothiophene-2-carboxylic acid contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 285.94 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.
