Chemical Structure
Description
CATO manufactures (5-Fluorobenzo[d]isoxazol-3-yl)methanesulfonamide 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.
(5-Fluorobenzo[d]isoxazol-3-yl)methanesulfonamide (CAS 68291-99-6) is a high-purity analytical reference standard with the molecular formula C8H7FN2O3S and a molecular weight of 230.22 g/mol.
(5-Fluorobenzo[d]isoxazol-3-yl)methanesulfonamide (C8H7FN2O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
