Description
CATO manufactures Difluoromethanesulfonyl fluoride 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.
Difluoromethanesulfonyl fluoride (CAS 1554-47-8) is a high-purity analytical reference standard with the molecular formula CHF3O2S and a molecular weight of 134.08 g/mol.
Difluoromethanesulfonyl fluoride (CHF3O2S) contains a sulfone group, fluorine substitution. Halogen substitution raises its density and boiling point; 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
