82-43-9 9,10-Anthracenedione, 1,8-dichloro- Anthraquinone, 1,8-dichloro- 1,8-Dichloroanthraquinone 4-07-00-02560 (Beilstein Handbook Reference) AI3-38302 BRN 1979205 1,8-Dichloranthrachinon [Czech] 1,8-Dichloro-9,10-anthraquinone EINECS 201-420-9 NSC 7209 1,8-Dichloranthrachinon (C14H18Cl2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, 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.
