01 · Identification
What Chrysene is
Chrysene is red blue fluorescent orthorhombic plates from benzene, acetic acid. Its molecular formula is C18H12 and its molecular weight is 228.3 g/mol. It boils at 448 °C, melts at 255 °C.
Under the GHS it carries the signal word Danger. It is classed as carcinogens.
02 · GHS classification
Hazards and label elements
Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.
| Code | Hazard statement |
|---|---|
| H350 | May cause cancer <state route of exposure if it is conclusively proven that no other routes of exposure cause the hazard>. |
| H341 | Suspected of causing genetic defects <state route of exposure if it is conclusively proven that no other routes of exposure cause the hazard>. |
| H400 | Very toxic to aquatic life. |
| H410 | Very toxic to aquatic life with long lasting effects. |
Precautionary statements: P201, P273, P280, P308, P313, P391, P501

04 · Handling and storage
Storing and handling Chrysene
Storage conditions
Keep container tightly closed in a dry and well-ventilated place.
Source: Hazardous Substances Data Bank (HSDB)
Incompatible materials
Incompatible materials: Strong oxidizing agents.
Source: Hazardous Substances Data Bank (HSDB)
Reactivity
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.
