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 3-(Pentafluoro-lambda6-sulfanyl)benzenesulfonyl Chloride.
CATO supplies 3-(Pentafluoro-lambda6-sulfanyl)benzenesulfonyl Chloride (CAS 1211520-62-5), a certified reference material (molecular formula C6H4ClF5O2S2, MW 302.67 g/mol) for analytical method development and quality control.
3-(Pentafluoro-lambda6-sulfanyl)benzenesulfonyl Chloride (C6H4ClF5O2S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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 3-(Pentafluoro-lambda6-sulfanyl)benzenesulfonyl 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.
