This chemical is primarily used as a coupling agent in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It facilitates the formation of peptide bonds by activating carboxyl groups, making it essential for the efficient production of peptides in pharmaceutical and biochemical research. Additionally, it is employed in organic synthesis for the preparation of amides, esters, and other derivatives, owing to its ability to enhance reaction efficiency and yield. Its stability and reactivity make it a valuable reagent in laboratories focused on developing bioactive compounds and complex organic molecules.
