Benzene, an organic compound, is the simplest aromatic hydrocarbon with a chemical formula of C6H6. At room temperature, it is a sweet, flammable, colorless and transparent liquid with carcinogenic toxicity and a strong aromatic odor. It is insoluble in water, easily soluble in organic solvents, and can also be used as an organic solvent itself. The ring system of benzene is called benzene ring, and the structure after removing a hydrogen atom from the benzene ring is called phenyl, which is represented by Ph, so the chemical formula of benzene can also be written as PhH. Benzene is a basic petrochemical raw material, and its output and production technology are one of the symbols of a country's petrochemical development level.

On October 27, 2017, the list of carcinogens published by the World Health Organization's International Agency for Research on Cancer was preliminarily sorted out for reference, and benzene was included in the list of Class I carcinogens.
