Description
Yellow, needle-like crystals that are derived from anthracene or phthalic anhydride. The name "anthraquinone" was derived from the word "anthracene", a component in coal tar that was used for numerous synthetic dyes, such as alizarin. Anthraquinone may be detected by the appearance of a red color on treatment with alkali, zinc powder, and water.
See also anthraquinone dye.
