Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
methyl 1-[(chlorosulfonyl)methyl]cyclopentane-1-carboxylate (CAS 1803570-67-3), molecular formula C8H13ClO4S and molecular weight 240.70 g/mol, is a CATO reference standard with documented purity and traceability.
methyl 1-[(chlorosulfonyl)methyl]cyclopentane-1-carboxylate (C8H13ClO4S) 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 methyl 1-[(chlorosulfonyl)methyl]cyclopentane-1-carboxylate 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.
