CATO supplies 4-(Sulfooxy)dibenz[b,f][1,4]oxazepin-11(10H)-one (CAS 88373-19-7), a certified reference material (molecular formula C13H9NO6S, MW 307.28 g/mol) for analytical method development and quality control.
4-(Sulfooxy)dibenz[b,f][1,4]oxazepin-11(10H)-one (C13H9NO6S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
