Used in bioorthogonal chemistry, this chemical is incorporated into proteins through genetic encoding. It allows for site-specific labeling and modification of proteins, enabling researchers to study protein function and interactions in live cells. The azide group reacts selectively with alkynes via click chemistry, facilitating the attachment of fluorescent dyes, affinity tags, or other functional groups. This makes it valuable in proteomics, drug discovery, and imaging applications. Additionally, it aids in understanding cellular processes and developing targeted therapies by providing precise control over protein modifications.
