Use

Pyrene can be used in the production of dyes such as indanthrone dyes and anthraquinone vat dyes. It can be used as raw material of organic synthesis. For example, it can be used for production of 1, 4, 5, 8-naphthalene tetracarboxylic acid via oxidation. It can be applied to dyes, synthetic resins and plastics; it can also be used for the manufacturing of vat dye Brilliant Orange GR and various kinds of other dyes. Moreover, it can also be used for the manufacturing of pesticides and plasticizers.
