Azido-aliphatic-azides are a class of compounds that contain azido and aliphatic functional groups. They are widely used in pharmaceutical research and development due to their unique chemical properties. Azido groups can undergo click chemistry reactions, which enable the attachment of a variety of functional groups to the azide moiety. This versatility makes azido-aliphatic-azides useful for a wide range of applications, including drug discovery and development. In addition, the aliphatic nature of these compounds makes them more stable and less reactive than other azido compounds, which enhances their usefulness in drug development.
