Chemical Structure
Description
The molecular framework of 6-Bromo-4-fluorobenzo[b]thiophene (C8H4BrFS) 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.
CATO supplies 6-Bromo-4-fluorobenzo[b]thiophene (CAS 826995-63-5), a certified reference material (molecular formula C8H4BrFS, MW 231.08 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
