Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(5-Ethylthiophen-2-yl)methanesulfonyl chloride (CAS 1184244-00-5), molecular formula C7H9ClO2S2 and molecular weight 224.73 g/mol, is a CATO reference standard with documented purity and traceability.
(5-Ethylthiophen-2-yl)methanesulfonyl chloride (C7H9ClO2S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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 (5-Ethylthiophen-2-yl)methanesulfonyl 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.
