Chemical Structure

3-Bromo-4-(bromomethyl)thiophene CAS 40032-80-2 chemical structure

Description

3-Bromo-4-(bromomethyl)thiophene (CAS 40032-80-2) is a high-purity analytical reference standard with the molecular formula C5H4Br2S and a molecular weight of 255.96 g/mol.

The molecular framework of 3-Bromo-4-(bromomethyl)thiophene (C5H4Br2S) is characterized by sulfur-containing functionality, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
