Hexaketocyclohexane hydrate (CAS 1894538-97-6), molecular formula C6O6H2O and molecular weight 186.08 g/mol, is a CATO reference standard with documented purity and traceability.
Hexaketocyclohexane hydrate (C6O6H2O) contains a carbohydrate-derived structure. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), Hexaketocyclohexane hydrate 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.
