HN₃, commonly known as hydrazoic acid, is a chemical compound consisting of nitrogen and hydrogen. It is a colorless, volatile liquid that is highly explosive and toxic. HN₃ is primarily used in the synthesis of azides, which are important in various chemical reactions and applications, including pharmaceuticals and explosives. Hydrazoic acid is notable for its unique structure, featuring a linear arrangement of atoms. It can be produced through the reaction of sodium azide with strong acids. Due to its instability, HN₃ must be handled with extreme caution in controlled environments to prevent accidental detonation.
