General description

Sodium Azide (NaN3) is a potent inhibitor – a water-soluble crystalline powder that′s odorless. Widely recognized for its versatile applications, it plays a pivotal role across molecular biology, cell culture, and biochemical research. It is also a metabolic inhibitor, which inhibits oxidative phosphorylation. In cell culture, it maintains the integrity of your cell lines.

Application

Sodium azide is suitable for use in histopathology to prepare and store tissue samples. Also used as a component of staining buffer (HEPES buffer) for whole mount immunolabelling.
Catalyst for:

  • Oxidative decarboxylation
  • Michael addition reactions

Reagent for synthesis of
  • Blue fluorescent copolymers
  • Metal phosphonates
  • Arenes via aminations
Baylis-Hillman acetates such as ethyl 2-(acetoxyphenylmethyl)acrylate can undergo nucleophilic displacement by sodium azide in aqueous medium to form ethyl (E)-2-azidomethyl-3-phenylpropenoate.

Biochem/physiol Actions

Sodium azide is clinically used as a preservative in diluting fluid for counting red blood cells. It prevents capping and internalization of fluorescent surface-bound antibodies in various scientific applications, including flow cytometry.
