Sodium azide is a good nitrogen liberating agent.
Acyl azide is a compound in which the hydroxy group of a carboxylic acid is replaced by the azido group (HN
Sodium azide is widely used as the propellant in
Due to its explosion hazard, sodium azide is of only limited value in industrial scale organic chemistry. In the laboratory, it is used in to introduce the azide functional group by displacement of . The azide functional group can thereafter be converted to an by reduction with either SnCl2 in ethanol or or a tertiary , such as in the , with or with in pyridine.
Sodium azide has caused deaths for decades. It is a severe poison. It may be fatal in contact with skin or if swallowed. Even minute amounts can cause symptoms. The toxicity of this compound is comparable to that of soluble alkali cyanides and the lethal dose for an adult human is about 0.7 grams. No toxicity has been reported from spent airbags.
0.02 - 0.2 %.Caution: Sodium azide is very toxic.
In fact, five states (VT, OR, MN, DE and NY) have enacted legislation that mandates that airbags with sodium azide be deployed or removed from a vehicle before it is wrecked or dismantled (see links to each of the 5 states’ policies below).

The same reaction occurs upon heating the salt to approximately 300 °C. The sodium that is formed is a potential hazard alone and, in automobile airbags, it is converted by reaction with other ingredients, such as and . In the latter case, innocuous sodium silicates are generated. Sodium azide is also used in airplane escape chutes. Newer generation air bags contain or .
