Chemical Structure
Description
The occurrence of 4-bromo-7-chloro-benzothiophene is closely related to sulfur-containing functionality, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-bromo-7-chloro-benzothiophene (CAS 1427377-20-5), molecular formula C8H12BrClS and molecular weight 255.60 g/mol, is a CATO reference standard with documented purity and traceability.
4-bromo-7-chloro-benzothiophene (C8H12BrClS) contains sulfur-containing functionality, chlorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
CATO manufactures 4-bromo-7-chloro-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.
