01 · Identification
What 2-Nitronaphthalene is
2-Nitronaphthalene: colourless-to-yellow solid in various forms. It boils at 304 °C, melts at 78.9 °C, is practically insoluble in water.
Under the GHS it carries the signal word Danger.
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>. |
| H411 | Toxic to aquatic life with long lasting effects. |
Precautionary statements: P201, P273, P280, P308, P313, P391, P501

Reactivity
2-NITRONAPHTHALENE is non-flammable but combustible (flash point 160 °C). Dust forms explosive mixtures with air. Heating or burning releases toxic and corrosive gases. Incompatible with strong oxidizing agents. Can serve as an oxidizing agent and so react with reducing agents such as hydrides, sulfides and nitrides. Such reactions may be vigorous and may culminate in a detonation. May explode in the presence of strong bases such as sodium or potassium hydroxide even in the presence of water or organic solvents.
