This chemical is widely used in peptide synthesis as a coupling reagent. It facilitates the formation of peptide bonds between amino acids, making it essential in the production of peptides for pharmaceutical and biochemical research. Its effectiveness in activating carboxyl groups ensures high yields and minimal racemization, which is critical for maintaining the integrity of synthesized peptides. Additionally, it is employed in organic synthesis for the preparation of amides, esters, and other complex molecules, owing to its stability and efficiency in promoting reactions under mild conditions. Its application extends to solid-phase peptide synthesis, where it enhances the stepwise assembly of peptide chains on solid supports.
