Description

General description

Sodium azide is commonly used as a bacteriostatic preservative for biological samples and also as a source to generate gas in automobile airbags. It is also a metabolic inhibitor, which inhibits oxidative phosphorylation.

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.

Catalyst for:

• Oxidative decarboxylation
• Michael addition reactions

Reagent for synthesis of

• Blue fluorescent copolymers
• Metal phosphonates
• Arenes via aminations

Involved in regioselective synthesis of prianosin B

Packaging

5, 25, 100, 500 g in poly bottle
