8,9-Dimethoxy-3-(propan-2-yl)-5-sulfanylidene-2H,3H,5H,6H-imidazo[1,2-c]quinazolin-2-one (CAS 1008206-85-6), molecular formula C15H17N3O3S and molecular weight 319.38 g/mol, is a CATO reference standard with documented purity and traceability.
8,9-Dimethoxy-3-(propan-2-yl)-5-sulfanylidene-2H,3H,5H,6H-imidazo[1,2-c]quinazolin-2-one (C15H17N3O3S) 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).
As a certified reference material (CRM), 8,9-Dimethoxy-3-(propan-2-yl)-5-sulfanylidene-2H,3H,5H,6H-imidazo[1,2-c]quinazolin-2-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
