This chemical is widely used as a coupling reagent in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It facilitates the formation of peptide bonds between amino acids, ensuring high efficiency and minimal racemization. Its stability and reactivity make it a preferred choice for synthesizing complex peptides and proteins in pharmaceutical research and biotechnology. Additionally, it is employed in organic synthesis for activating carboxylic acids, enabling the formation of esters, amides, and other derivatives. Its application extends to the production of bioactive compounds and materials with specific functional properties.
