C14H10 A colorless, crystalline hydrocarbon; melts at about 100°C; the nucleus is produced by the degradation of certain alkaloids; used in the synthesis of dyes and drugs.



a tricyclic aromatic hydrocarbon occurring as colorless crystals that are insoluble in water and soluble in organic solvents. Phenanthrene has a melting point of 101°C and a boiling point of 340°C. The structural formula is

Phenanthrene solutions possess a light blue fluorescence. The compound, together with its linear isomer anthracene, is contained in coal tar. Derivatives of the compound in which the phenanthrene rings are partially or completely hydrogenated are commonly encountered in plants and animals (resin acids, steroids). Phenanthrene is used in the production of dyes.
