Chemical Structure
Description
As a certified reference material (CRM), 2,3-Dihydro-9,10-dihydroxy-1,4-anthracenedione 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.
2,3-Dihydro-9,10-dihydroxy-1,4-anthracenedione (CAS 17648-03-2), molecular formula C14H10O4 and molecular weight 242.23 g/mol, is a CATO reference standard with documented purity and traceability.
2,3-Dihydro-9,10-dihydroxy-1,4-anthracenedione (C14H10O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
