Physical & chemical behavior

Reactivity
Stable under ordinary conditions of use and storage.

Ammonia, hydrogen cyanide and oxides of carbon and nitrogen may be produced when heated to decomposition.

This product is incompatible with acidic materials such as nitric acid, sulphuric acid, hydrochloric acid, etc., leading to an exothermic reaction. Violent reactions can occur with strong oxidizing agents.

Never expose this liquid or its vapours to heat, flame, or ignition sources. Avoid contact with any acids or strong oxidizing agents.
