Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-(2-Methoxyethyl)-1H-pyrazole-4-sulfonyl Chloride (CAS 1183082-06-5), molecular formula C6H9ClN2O3S and molecular weight 224.67 g/mol, is a CATO reference standard with documented purity and traceability.
1-(2-Methoxyethyl)-1H-pyrazole-4-sulfonyl Chloride (C6H9ClN2O3S) contains an amide group, 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 1-(2-Methoxyethyl)-1H-pyrazole-4-sulfonyl 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.
