Description
CATO manufactures (3,3-difluorocyclobutyl)methanesulfonyl 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.
(3,3-difluorocyclobutyl)methanesulfonyl chloride (CAS 1622903-44-9), molecular formula C5H7ClF2O2S and molecular weight 204.62 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, (3,3-difluorocyclobutyl)methanesulfonyl chloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 204.62 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
