Chemical Structure

3-Bromo-5-chloro-1-benzothiophene CAS 32969-26-9 chemical structure

Description

The occurrence of 3-Bromo-5-chloro-1-benzothiophene is closely related to sulfur-containing functionality, chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-Bromo-5-chloro-1-benzothiophene (CAS 32969-26-9), a certified reference material (molecular formula C8H4BrClS, MW 247.54 g/mol) for analytical method development and quality control.

The molecular framework of 3-Bromo-5-chloro-1-benzothiophene (C8H4BrClS) is characterized by sulfur-containing functionality, chlorine/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.

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.

As a certified reference material (CRM), 3-Bromo-5-chloro-1-benzothiophene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
