Description and Uses

Pyrene is an organic compound with chemical formula C16H10, light yellow monoclinic crystal (pure product is colorless), aromatic, combustible[1], insoluble in water and soluble in ethanol and ether. It can carry out electrophilic substitution, such as halogenation, nitration, sulfonation and other reactions. Pyrene mainly exists in the distillate of coal tar pitch. Pyrene is an organic synthetic raw material, which can be oxidized to produce 1,4,5,8-naphthalene tetracarboxylic acid, which is used in dyes, synthetic resins, disperse dyes and engineering plastics; After acylation, the vat dye brilliant orange GR and other dyes can be prepared. It can also make pesticides, plasticizers, etc. On October 27, 2017, the list of carcinogens published by the international agency for research on cancer of the World Health Organization was preliminarily sorted out for reference. Pyrene was included in the list of three types of carcinogens.

Pyrene and its derivatives are used commercially to make?dyes?and dye precursors, for example?pyranine?and naphthalene-1,4,5,8-tetracarboxylic acid. It is used as a probe to determine solvent environments and fluorescence spectroscopy.
