Sodium azide is a chemical compound used as a preservative in laboratory reagents and buffers to prevent microbial growth. It is also used in the synthesis of other chemicals and as a propellant in airbags.
In research, sodium azide inhibits cytochrome oxidase, making it a useful tool for studying cellular respiration and mitochondrial function. However, it is highly toxic and can form explosive compounds when exposed to metals or acids.
Proper safety protocols, including the use of gloves and fume hoods, are essential when handling sodium azide.
