2-Amino-6-iodo-8-methylquinazolin-4(1H)-one (CAS 830343-37-8), molecular formula C9H8IN3O and molecular weight 301.08 g/mol, is a CATO reference standard with documented purity and traceability.
2-Amino-6-iodo-8-methylquinazolin-4(1H)-one (C9H8IN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution. Halogen substitution raises its density and boiling point; 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.
