Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
764-08-9 CTK2G7807 Chlorosulfuric acid, 2,2-dimethylpropyl ester (CAS 764-08-9) is a high-purity analytical reference standard with the molecular formula C5H11ClO3S and a molecular weight of 186.66 g/mol.
764-08-9 CTK2G7807 Chlorosulfuric acid, 2,2-dimethylpropyl ester (C5H11ClO3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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 764-08-9 CTK2G7807 Chlorosulfuric acid, 2,2-dimethylpropyl ester 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.
