Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethane-1,2-disulfonyl dichloride.
Ethane-1,2-disulfonyl dichloride (CAS 31469-08-6), molecular formula C2H4Cl2O4S2 and molecular weight 227.09 g/mol, is a CATO reference standard with documented purity and traceability.
Ethane-1,2-disulfonyl dichloride (C2H4Cl2O4S2) contains a sulfone group, a carboxylic acid 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Ethane-1,2-disulfonyl dichloride 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.
