Azide is a chemical compound that contains the azide ion, which consists of three nitrogen atoms connected in a linear arrangement (N₃⁻). It is often used in organic synthesis and as a precursor for various nitrogen-containing compounds. Azides can be highly reactive and are known for their explosive properties, especially when they are in a solid state. In addition to its use in laboratories, azides are also found in some applications, such as in automobile airbags, where they help generate gas rapidly upon ignition. However, due to their potential hazards, handling azides requires strict safety precautions.
