  1,4-Dihydroxyanthraquinone/Quinizarine   C .I. NO:1,4-Dihydroxyanthraquinone CAS NO: 81-64-1 Molecular Formula: C14H8O4 Molecular Weight: 240.2109 Application: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 1,4-Dihydroxyanthraquinone. It has been studied as a long range emissive ratiometric fluorescent probe for live cell imaging.
