Product Description

Sodium Azide

Application Notes

Sodium azide used as a preservative for laboratory reagents; a bacteriostatic agent in storage solutions. Inhibits gram negative flora so is therefore included in culture media for the selective isolation of Streptococci and Staphylococci. It has been used to avoid bacterial contamination during RPC-5 column chromatography of DNA fragments.Catalyst for:• Oxidative decarboxylation• Michael addition reactionsReagent for synthesis of• Blue fluorescent copolymers• Metal phosphonates• Arenes via aminationsInvolved in regioselective synthesis of prianosin B

Usage Statement

Unless specified otherwise, MP Biomedical's products are for research or further manufacturing use only, not for direct human use. For more information, please contact our customer service department.

Key Applications

Preservative | Bacteriostatic agent | Chromatography | Probe reagent | Mutagen

Biochemical Physiological Actions Sodium Azide is an inhibitor of peroxidase, myeloperoxidase, superoxide dismutase, galactose oxidase, catalase, haemoprotein enzymes and O2 evolution in photosynthesis. The mechanism of its inhibition and toxicity may be due to metal ion complexation and displacement from enzyme.
