A crystalline solid. Denser than water and insoluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit spread to the environment. Toxic by ingestion. Used to make other chemicals.
Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as Chrysene, 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.
Air & Water Reactions
Insoluble in water.
Purify chrysene by chromatography on alumina from pet ether in a darkened room. Its solution in *C6H6 is passed through a column of decolorising charcoal, then crystallised by concentrating the eluate. It has also been purified by crystallising from *C6H6 or *C6H6/pet ether, and by zone refining. [Gorman et al. J Am Chem Soc 107 4404 1985]. It is freed from 5H-benzo[b]carbazole by dissolving it in N,N-dimethylformamide and successively adding small portions of alkali and iodomethane until the fluorescent colour of the carbazole anion no longer appears when alkali is added. The chrysene (and alkylated 5H-benzo[b]carbazole) separate on addition of water. Final purification is by crystallisation from ethylcyclohexane and/or from 2-methoxyethanol [Bender et al. Anal Chem 36 1011 1964]. It can be sublimed in a vacuum. [Beilstein 5 IV 2554.]
Chrysene is a polycyclic aromatic hydrocarbon (PAH) consisting of four fused benzene rings. Some of its derivatives such as electroluminescent 3, 6, 9, 12-tetrasubstituted chrysenes are useful in electroluminescent applications such as being used in the organic light emitting dioxide (OLED). They are also relates to electronic devices in which the active layer includes such a chrysene composition. Chrysene is a potential carcinogen.

Some may burn but none ignite readily. Containers may explode when heated. Some may be transported hot.
