Used primarily in biochemical research to study protein synthesis and identify newly synthesized proteins. It acts as an analog of puromycin, allowing for the selective labeling and tracking of proteins in living cells. This enables researchers to visualize and analyze protein production in real-time, providing insights into cellular processes and mechanisms. Its propargyl group facilitates click chemistry, making it compatible with various detection and purification techniques, enhancing its utility in proteomics and molecular biology studies.
