Used as an activating agent in peptide synthesis, this compound helps form amide bonds by converting carboxylic acids into active esters. It is commonly employed in coupling reactions, especially with amines, to improve reaction efficiency and yield. Its structure supports solubility in polar solvents and enhances stability of the activated intermediate, making it valuable in solid-phase synthesis and bioconjugation processes. Frequently used in the preparation of pharmaceuticals and biologically active molecules where mild reaction conditions are required.
