Ethyl azide (C2H5N3) is an explosive compound sensitive to rapid heating, shock or impact. It has exploded when heated to room temperature.[1][2] When heated to decomposition it emits toxic fumes of NOx.[3][4]

It is irritating to eyes, respiratory system and skin.


Ethyl azide is used for organic synthesis.
