Widely used as a coupling reagent in peptide synthesis, it facilitates the formation of amide bonds between amino acids, enhancing efficiency and yield. It is particularly valued for its mild reaction conditions and reduced risk of racemization, making it suitable for sensitive peptide sequences. Additionally, it finds application in organic synthesis for the preparation of various heterocyclic compounds. Its stability and effectiveness in aqueous and organic solvents make it a versatile choice in pharmaceutical and biotechnological research.
