Use

Anthracene is an aromatic hydrocarbonwith three fused rings, and is obtained by the distillationof crude oils. The main useis in the manufacture of dyes.It is an important source of dyestuffs. Like most PAHs, anthracene is used to make dyes, plastics, and pesticides. It has been used to make smoke screens and scintillation counter crystals.
