Chemical Structure
Description
CATO supplies 6-chlorobenzofuran-3-sulfonyl chloride (CAS 2231234-34-5), a certified reference material (molecular formula C8H12Cl2O3S, MW 259.15 g/mol) for analytical method development and quality control.
The molecular framework of 6-chlorobenzofuran-3-sulfonyl chloride (C8H12Cl2O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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), 6-chlorobenzofuran-3-sulfonyl chloride 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.
