Key Properties
Sodium azide (NaN3) is a highly toxic, white crystalline powder that serves as an analytical reagent with a purity of 99% AR grade. It is primarily used in laboratory settings for its bacteriostatic properties and is known for its strict toxicity precautions. Sodium azide is notable for its ability to release nitrogen gas upon decomposition, making it useful in various chemical reactions. Due to its hazardous nature, it is classified under UN 1687 and requires careful handling and storage to prevent accidental exposure or reactions with incompatible materials.
Also known as Sodium azide, Azide of sodium.
