What is the 1,4-DIHYDROXYANTHRAQUINONE?

1,4-DIHYDROXYANTHRAQUINONE is orange to red-brown crystalline powder, while it's Molecular Formula is C14H8O4. orange to red-brown crystalline powder 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.

What is the CAS number for 1,4-DIHYDROXYANTHRAQUINONE?

The CAS number of 1,4-DIHYDROXYANTHRAQUINONE is 81-64-1.

What is 1,4-DIHYDROXYANTHRAQUINONE (81-64-1) used for?

1,4-Dihydroxyanthraquinone, also known as quinizarin, is an organic dye molecule with an aromatic structure. It is a derivative of anthraquinone bearing hydroxyl moieties at the 1and 4-positions. 1,4-DIHYDROXYANTHRAQUINONE is orange-red in color and exhibits properties such as insolubility in water, solubility in ether and organic solvents, and fluorescence in concentrated sulfuric acid. It may find uses in various industries, including pharmaceutical, biochemical, and dye industries, due to its resistance to degradation.InChI:InChI=1/C14H8O4/c15-9-5-6-10(16)12-11(9)13(17)7-3-1-2-4-8(7)14(12)18/h1-6,15-16H
