Description
CATO manufactures 4-(Pentafluoro-λ6-sulfanyl)benzene-1-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.
CATO supplies 4-(Pentafluoro-λ6-sulfanyl)benzene-1-sulfonyl chloride (CAS 1211516-26-5), a certified reference material (molecular formula C6H4ClF5O2S2, MW 302.67 g/mol) for analytical method development and quality control.
The molecular framework of 4-(Pentafluoro-λ6-sulfanyl)benzene-1-sulfonyl chloride (C6H4ClF5O2S2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/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.
