Description 1,4-Dihydroxyanthraquinone is an organic dye molecule with an aromatic structure. It is a derivative of anthraquinone bearing hydroxyl moieties. They may find uses in pharmacological, biochemical and dye industries. Anthraquinone dye are resistant to degradation.1,4-Dihydroxyanthraquinone may be used in the synthesis of cyclopentanoids by cyclization of α,β-unsaturated aldehyde with 1, 4 1,4-Dihydroxyanthraquinone. It has been studied as a long range emissive ratiometric fluorescent probe for live cell imaging.
