Used as an activating agent in peptide synthesis, this compound facilitates the formation of amide bonds by converting carboxylic acids into active esters. It is particularly effective in coupling reactions where high efficiency and minimal racemization are required. Its structure allows for good solubility in polar aprotic solvents, making it suitable for use in solid-phase and solution-phase synthesis. Commonly employed in the preparation of pharmaceutical intermediates and bioconjugates, it enables mild reaction conditions and high yields.
