Physical description & handling notes

• Chrysene appears as 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.
• Other Solid
• Crystals derived from distillation of coal tar; [Hawley]
• COLOURLESS-TO-BEIGE CRYSTALS OR POWDER.
• Crystalline solid.
• Red blue fluorescent orthorhombic plates from benzene, acetic acid

GHS Hazard Classification

Reported hazard statements	H341, H350, H400, H410, H351

Documented Uses

• Used in organic synthesis and in research; [HSDB]
• Chrysene, alone, is not produced in the United States except as a laboratory research chemical ...
• Substance listed with specific concentration in tattoo ink and/or permanent make up according to EU Commission Regulation 2020/2081. The concentration limit (by weight) is 0.00005%.
• PAHs are released into the environment via the combustion of fossil fuels, coke oven emissions and vehicle exhausts, as well as naturally from forest fires and volcanic eruptions. PAHs from these sources may contaminate nearly water systems. They are also found in coal tar and charbroiled food. Chrysene is also used in the manufacture of some wood preservatives and dyes. (L10)
• Synthesis by heating H2 and acetylene to 800 °C.
• Is formed during distillation of coal, in very small amount during distillation or pyrolysis of many fats and oils.
