Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromothiophene-2-sulfonyl chloride.
CATO supplies 4-Bromothiophene-2-sulfonyl chloride (CAS 185329-76-4), a certified reference material (molecular formula C4H2BrClO2S2, MW 261.54 g/mol) for analytical method development and quality control.
The molecular framework of 4-Bromothiophene-2-sulfonyl chloride (C4H2BrClO2S2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4-Bromothiophene-2-sulfonyl chloride 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.
