Chrysene is a polycyclic aromatic hydrocarbon (PAH) with the molecular formula C
12 that consists of four fused benzene rings. It is a natural constituent of coal tar, from which it was first isolated and characterized. It is also found in creosote, a chemical used to preserve wood.
Chrysene is formed in small amounts during the burning or distillation of coal, crude oil, and plant material.
The name "chrysene" originates from Greek Χρύσoς (chrysos), meaning "gold", and is due to the golden-yellow color of the crystals of the hydrocarbon, thought to be the proper color of the compound at the time of its isolation and characterization. However, high purity chrysene is colorless, the yellow hue being due to the traces of its yellow-orange isomer tetracene, which cannot be separated easily.
Chrysene is used in the manufacture of some dyes.
