HazardClass: 6.1(b)
PackingGroup: III

Dibenzo(A,E)Pyrene Specification

General description about Dibenzo(A,E)Pyrene (192-65-4). It is a yellow crystals.
Air & Water Reactions: Dust/air mixtures may ignite and explode. Insoluble in water.
Reactivity Profile: Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as Dibenzo(A,E)Pyrene(192-65-4) , and strong oxidizing agents. They can react exothermically with bases and with diazo compounds. Substitution at the benzene nucleus occurs by halogenation (acid catalyst), nitration, sulfonation, and the Friedel-Crafts reaction.
