Used in biochemical research for the study of protein synthesis and enzyme mechanisms, particularly in the development of novel enzymes and proteins. It serves as a key intermediate in the synthesis of modified peptides and proteins, enabling the incorporation of non-natural amino acids into polypeptides. This chemical is also utilized in the field of genetic code expansion, allowing researchers to introduce specific functional groups into proteins for advanced studies on protein structure and function. Additionally, it finds applications in the development of therapeutic proteins and bioconjugates, enhancing their stability and efficacy.
