Used in the development of peptide-based drugs, it serves as a key building block for introducing alkyne functional groups into peptides. This allows for click chemistry applications, enabling the conjugation of peptides with other molecules like fluorescent dyes or drugs for targeted delivery. It is also employed in the study of protein interactions and labeling, facilitating research in biochemistry and molecular biology. Additionally, it plays a role in the synthesis of bioactive compounds for potential therapeutic applications, particularly in cancer research and diagnostics.
