anthracene (ăn`thrəsēn), C14H10, solid organic compound derived from coal tar. It melts at 218°C; and boils at 354°C;. When pure it is colorless and has a violet fluorescence; it darkens when exposed to sunlight. Anthracene is insoluble in water but is quite soluble in carbon disulfide and somewhat soluble in ethanol, methanol, benzene, chloroform, and other organic solvents. It is readily oxidized to form anthraquinone, the parent compound of the alizarin alizarin , or 1,2-dihydroxyanthraquinone, mordant vegetable dye obtained originally from the root of the madder plant (Rubia tinctorum), in which it occurs as a glucoside. The term also includes a group of synthetic dyestuffs prepared from coal-tar derivatives.

The molecular structure of anthracene consists of three benzenelike rings joined side by side; it is thus an aromatic compound aromatic compound, any of a large class of compounds that includes benzene and compounds that resemble benzene in certain of their chemical properties. Originally applied to a small class of pleasant-smelling chemicals derived from vegetables, it now encompasses a ..... Click the link for more information. . It is the first member of the anthracene series, a group of aromatic hydrocarbons that are structurally related to it and have the general formula CnH2n−18. anthracene [′an·thrə‚sēn] (organic chemistry) C14H10A crystalline tricyclic aromatic hydrocarbon, colorless when pure, melting at 218°C and boiling at 342°C; obtained in the distillation of coal tar; used as an important source of dyestuffs, and in coating applications.
