Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,2-difluoro-2H-1,3-benzodioxole-5-sulfonyl chloride (CAS 313681-67-3) is a high-purity analytical reference standard with the molecular formula C7H9ClF2O4S and a molecular weight of 262.66 g/mol.
2,2-difluoro-2H-1,3-benzodioxole-5-sulfonyl chloride (C7H9ClF2O4S) 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.
CATO manufactures 2,2-difluoro-2H-1,3-benzodioxole-5-sulfonyl 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.
