Chemical Structure
Description
The occurrence of 6-Bromo-3,5-dichloro-7-fluorobenzo[c]isothiazole is closely related to a nitrile group, sulfur-containing functionality, fluorine/chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6-Bromo-3,5-dichloro-7-fluorobenzo[c]isothiazole (CAS 2230875-11-1) is a high-purity analytical reference standard with the molecular formula C7HBrCl2FNS and a molecular weight of 300.96 g/mol.
The molecular framework of 6-Bromo-3,5-dichloro-7-fluorobenzo[c]isothiazole (C7HBrCl2FNS) is characterized by a nitrile group, sulfur-containing functionality, fluorine/chlorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
