CATO supplies (10R)-2-chloro-10-methyl-4-(1-(methylsulfonyl)cyclopropyl)-6a,7,9,10-tetrahydro-6H-[1,4]oxazino[4,3-d]pyrimido[5,4-b][1,4]oxazine (CAS 2161304-95-4), a certified reference material (molecular formula C14H18ClN3O4S, MW 359.83 g/mol) for analytical method development and quality control.
(10R)-2-chloro-10-methyl-4-(1-(methylsulfonyl)cyclopropyl)-6a,7,9,10-tetrahydro-6H-[1,4]oxazino[4,3-d]pyrimido[5,4-b][1,4]oxazine (C14H18ClN3O4S) 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).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
