The molecular framework of 4,5-Dichloro-3H-1,2-dithiole-3-thione (C3Cl2S3) is characterized by sulfur-containing functionality, chlorine 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.
4,5-Dichloro-3H-1,2-dithiole-3-thione (CAS 57248-64-3) is a high-purity analytical reference standard with the molecular formula C3Cl2S3 and a molecular weight of 203.13 g/mol.
