General Information

• Sodium azide is a precursor for preparing inorganic azides such as lead azide and silver azide
• One mechanism of action associated with this compound can be related to the inhibition of mitochondrial ATPase, that consequently suppresses oxidative phosphorylation

Applications

• Sodium azide is an inorganic compound with antibacterial and mutagenic activities mainly used in biological samples
• Sodium azide inhibits cytochrome oxidase in gram-negative bacteria. However, its antibacterial capacity is more limited in some gram-positive bacteria (streptococci, pneumococci, lactobacilli), presenting intrinsic resistance
• Sodium azide is used for the introduction of an azide group to prepare a desired compound
• It is useful in biochemical approaches as a probe reagent and a preservative
• This compound can be used to synthetize blue fluorescent copolymers and metal phosphonates
