Chemical Structure
Description
The molecular framework of 2-bromo-3-(methylsulfinyl)thiophene (C5H5BrOS2) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, 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.
2-bromo-3-(methylsulfinyl)thiophene (CAS 133362-12-6) is a high-purity analytical reference standard with the molecular formula C5H5BrOS2 and a molecular weight of 225.13 g/mol.
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.
