This chemical is widely used as a coupling reagent in peptide synthesis, facilitating the formation of amide bonds between amino acids. It is particularly valued for its efficiency and mild reaction conditions, making it suitable for synthesizing complex peptides and proteins. Additionally, it is employed in organic synthesis for the preparation of esters, amides, and other derivatives, often in pharmaceutical and biochemical research. Its stability and selectivity also make it a preferred choice in solid-phase peptide synthesis, ensuring high yields and minimal side reactions.
