DescriptionECHEMI Editorial ReferenceViolet powder
1,4-Diaminoanthraquinones (DAAQs) are an active substance. Because of its quinone function (reduction), two amine functions (oxidation) and aromatic base structures are combined that stabilize the reduced and oxidized species via electron delocalization. Therefore， they have five different electrochemical oxidation states: a neutral state, two reduced states, and two oxidized states. However, their practical availability is limited due to their low solubility in commonly used polar organic solvents.
Purify the anthraquinone by thin-layer chromatography on silica gel using toluene/acetone (9:1) as eluent. The main band is scraped off and extracted with MeOH. The solvent is evaporated, and the quinone is dried in a drying pistol [Land et al. J Chem Soc, Faraday Trans 1 72 2091 1976]. It crystallises from EtOH (m 269o) in dark violet crystals. Store it in sealed ampoules in the dark. [Beilstein 14 H 197, 14 II 113, 14 III 437, 14 IV 458.]CertificatesBasic Info-
