Chemical Structure

3-Bromo-2,4-dimethylthiophene CAS 79485-96-4 chemical structure

Description

Based on its molecular formula C6H7BrS, 3-Bromo-2,4-dimethylthiophene contains sulfur-containing functionality, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 191.09 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).

CATO supplies 3-Bromo-2,4-dimethylthiophene (CAS 79485-96-4), a certified reference material (molecular formula C6H7BrS, MW 191.09 g/mol) for analytical method development and quality control.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
