Description
CATO manufactures 1-Chloro-2-trifluoromethanesulfonylethane 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.
1-Chloro-2-trifluoromethanesulfonylethane (CAS 18450-56-1) is a high-purity analytical reference standard with the molecular formula C3H4ClF3O2S and a molecular weight of 196.58 g/mol.
1-Chloro-2-trifluoromethanesulfonylethane (C3H4ClF3O2S) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
