Description
CATO manufactures 4-bromo-5-fluoro-1-benzothiophene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 4-bromo-5-fluoro-1-benzothiophene (CAS 826995-66-8), a certified reference material (molecular formula C8H4BrFS, MW 231.08 g/mol) for analytical method development and quality control.
The molecular framework of 4-bromo-5-fluoro-1-benzothiophene (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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
