This chemical is primarily used as a coupling agent in peptide synthesis, facilitating the formation of peptide bonds between amino acids. It is particularly valued for its efficiency in solid-phase peptide synthesis, where it helps achieve high yields and purity. Additionally, it is employed in organic synthesis for the activation of carboxylic acids, enabling the formation of esters, amides, and other derivatives. Its stability and reactivity make it a preferred choice in complex chemical reactions, especially in pharmaceutical research and development.
