Application

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.
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

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.

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.
