This chemical is widely used in peptide synthesis as a coupling reagent. It facilitates the formation of amide bonds between amino acids, making it essential in the production of peptides and proteins in laboratory settings. Its high efficiency and ability to minimize racemization make it a preferred choice in solid-phase peptide synthesis. Additionally, it is employed in organic synthesis for activating carboxylic acids, enabling the formation of esters, amides, and other derivatives. Its stability and reactivity under mild conditions contribute to its versatility in various chemical reactions.
