Azide refers to a chemical compound that contains the azide ion, which is represented as N3⁻. This ion consists of three nitrogen atoms connected in a linear arrangement. Azides are often used in organic synthesis and can serve as precursors for various nitrogen-containing compounds. They are known for their high reactivity and can be explosive under certain conditions. One of the most common azides is sodium azide (NaN3), which is used in automotive airbags and as a preservative in laboratories. Due to their potential hazards, azides must be handled with care, and safety protocols are essential when working with these compounds.
