Chemical Structure
Description
The occurrence of 2-(chlorosulfonyl)-2-methylpropanoyl chloride is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-(chlorosulfonyl)-2-methylpropanoyl chloride (CAS 41138-76-5), a certified reference material (molecular formula C4H6Cl2O3S, MW 205.06 g/mol) for analytical method development and quality control.
2-(chlorosulfonyl)-2-methylpropanoyl chloride (C4H6Cl2O3S) 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.
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 2-(chlorosulfonyl)-2-methylpropanoyl 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.
