Description
CATO manufactures N-(Furan-2-ylmethylene)-4-methylbenzenesulfonamide 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.
N-(Furan-2-ylmethylene)-4-methylbenzenesulfonamide (CAS 13707-47-6), molecular formula C12H11NO3S and molecular weight 249.29 g/mol, is a CATO reference standard with documented purity and traceability.
N-(Furan-2-ylmethylene)-4-methylbenzenesulfonamide (C12H11NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
