It is used as an insect repellant and insect fumigant. The compound is used in the manufacture of celluloid, dyes, hydrogenated naphthalenes, oil fumes, smokeless powders and synthetic resins.
Azaindole can be regarded as the biological isostere of indole, and the molecular unit of indole plays a huge role in the life process. Many drug molecules contain indole units. Azaindole is an important heterocyclic intermediate with good biological and medicinal value, and is the core structure of many drugs, such as antitumor drugs, dopamine D4 receptors, kinase inhibitors, thrombin inhibitors, etc. Therefore, it has a wide range of application value in medical research.
