Chemical Structure
Description
The molecular framework of 2,4-Dibromo-3-trifluoromethylbenzenethiol (C7H3Br2F3S) is characterized by sulfur-containing functionality, fluorine/bromine substitution, an aromatic ring system. 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.
2,4-Dibromo-3-trifluoromethylbenzenethiol (CAS 1349708-77-5) is a high-purity analytical reference standard with the molecular formula C7H3Br2F3S and a molecular weight of 335.97 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.
