Description
CATO manufactures methyl 5-chlorosulfonyl-2-fluoro-benzoate 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.
methyl 5-chlorosulfonyl-2-fluoro-benzoate (CAS 1094460-86-2), molecular formula C8H12ClFO4S and molecular weight 258.69 g/mol, is a CATO reference standard with documented purity and traceability.
methyl 5-chlorosulfonyl-2-fluoro-benzoate (C8H12ClFO4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, 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.
