GENERAL DESCRIPTION & APPLICATIONS |
||
| Azide
contains the group -N3
represented as a resonance hybrid of two structures,
-N-N-≡N+
↔ -N=N+=N-.
Organic azides are compounds replaced by a hydrocarbon group as in alkyl or aryl
from hydrazoic acid and have general formula RN3. Acyl azide is a compound in
which the hydroxy group of a carboxylic acid is replaced by the azido group
(HN3). Hydrazide is an acyl hydrazine. Acyl (-CO) is an organic radical formed by
removal of a hydroxyl group from an organic acid (carboxyl group). Certain metallic azide salts are very explosive.
Organic azides are useful for the synthesis of target compounds. They act as electrophiles on the nitrogen attached to the carbon and have electron-donating character for the neighboring carbon. In the azide alkyne Huisgen cycloaddition, organic azides react as 1,3-dipoles. Examples of organic azides are the chemical reagent phenyl azide and the antiviral drug zidovudine (AZT). Another azide regular is tosyl azide here in reaction with norbornadiene in a nitrogen insertion reaction Sodium azide is a crystals; soluble in water and liquid ammonia; decomposes at 300C. Sodium azide rapidly explode and release nitrogen gas by impact, used as a propellant of automotive safety bag (inflating). Sodium Azide is used in the preparation of hydrazoic acid ((HN3), lead azide, explosives. Sodium azide is a good nitrogen liberating agent. It is used in organic synthesis including pharmaceuticals (such as Alfentanil; Azosemid; Broperamol;). It is used as a soil sterilizing agent, fungicide, and herbicide. Sodium azide is widely used as the propellant in airbags. Sodium azide is useful in the preparation of Agricultural Chemical (Insecticide, Fungicide, bactericide, wood preservative, Herbicide). In biochemistry, it inhibits cytochrome oxidase by binding irreversibly to the heme cofactor in a process similar to the action of carbon monoxide. it is an enzyme inhibitor and nematocide. It is a useful indicator and probe reagent. It is a cardiovascular agent and vasodilator agent. |
