This chemical is widely used as a coupling agent in peptide synthesis. It facilitates the formation of peptide bonds by activating carboxylic acids, making it essential in the production of peptides for pharmaceutical and biochemical research. Its stability and efficiency in organic solvents make it a preferred choice in solid-phase peptide synthesis. Additionally, it is employed in the preparation of other complex organic molecules, particularly in reactions requiring mild conditions and high yields. Its role in enhancing reaction specificity and reducing side products is highly valued in synthetic chemistry.
