In chemistry, azide (/ ˈ eɪ z aɪ d /, AY-zyd) is a linear, polyatomic anion with the formula N − 3 and structure − N=N + =N −. It is the conjugate base of hydrazoic acid HN 3 . Organic azides are organic compounds with the formula RN 3 , containing the azide functional group . [ 1 ]
Lead azide was a component of the six .22 (5.6 mm) caliber Devastator rounds fired from a Röhm RG-14 revolver by John Hinckley, Jr. in his assassination attempt on U.S. President Ronald Reagan on March 30, 1981. The rounds consisted of lead azide centers with lacquer-sealed aluminum tips designed to explode upon impact.
The oxygen diazide O(N 3) 2 has been suggested to be the intermediate in the formation of cyclic nitrous oxide N 2 O from OF 2 and NaN 3, but its existence has not yet been confirmed. [70] The parent sulfur azides S(N 3) 2 or S(N 3) 4 have not been synthesized and only theoretical calculations to their existence have been studied. [71]
Certain agencies may add or remove certain codes. For example, in the Los Angeles Police Department's radio procedures, Code 1 is not a response code, and its meaning is transferred to Code 2, the original meaning of which is transferred to the semi-official response code "Code 2-High". Additionally, some agencies use "Code 99" which means for ...
Barium azide can be used to make azides of magnesium, sodium, potassium, lithium, rubidium and zinc with their respective sulfates. [4] Ba(N 3) 2 + Li 2 SO 4 → 2 LiN 3 + BaSO 4. It can also be used as a source for high purity nitrogen by heating: Ba(N 3) 2 → Ba + 3 N 2. This reaction liberates metallic barium, which is used as a getter in ...

The compound hydrolyzes to hydrazoic acid: [3] (CH 3) 3 SiN 3 + H 2 O → (CH 3) 3 SiOH + HN 3. The compound adds to ketones and aldehydes to give the siloxy azides and subsequently tetrazoles: [1] (CH 3) 3 SiN 3 + R 2 CO → R 2 C(N 3)OSi(CH 3) 3. It ring-opens epoxides to give azido alcohols. It has been used in the Oseltamivir total synthesis.
