Product Description
Sodium Azide (NaN₃) is a white, crystalline, highly toxic inorganic compound widely used as a preservative, reagent, and propellant precursor. It serves as a source of pure nitrogen gas (N₂) and a powerful antimicrobial agent in laboratory and industrial applications.
In laboratories, Sodium Azide is frequently used as a biochemical preservative in reagents and buffers, while in research and manufacturing it acts as a nitrogen donor in azide synthesis, explosives, and airbags. Due to its high reactivity and toxicity, Sodium Azide must be handled strictly under controlled conditions by trained personnel.
