Description and Uses

1,4-Dihydroxyanthraquinone is used to color gasoline and some heating oils. It is used as an intermediate for the synthesis of indanthrene- and alizarin-derived dyes. It is also used to form lake pigments with calcium, barium and lead. It may be used in the synthesis of cyclopentanoids by cyclization of α,β-unsaturated aldehyde with 1,4-Dihydroxyanthraquinone. It has been studied as a long range emissive ratiometric fluorescent probe for live cell imaging.
