2-(tert-Butyl)-6-chlorobenzo[d]oxazole-7-sulfonamide (CAS 761448-08-2) is a high-purity analytical reference standard with the molecular formula C11H13ClN2O3S and a molecular weight of 288.75 g/mol.
2-(tert-Butyl)-6-chlorobenzo[d]oxazole-7-sulfonamide (C11H13ClN2O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. 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.
