The occurrence of 2-(Bromomethyl)-5-chlorothiophene is closely related to sulfur-containing functionality, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(Bromomethyl)-5-chlorothiophene (CAS 59311-22-7), molecular formula C5H4BrClS and molecular weight 211.51 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(Bromomethyl)-5-chlorothiophene (C5H4BrClS) is characterized by sulfur-containing functionality, chlorine/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.
