Used primarily as a coupling reagent in peptide synthesis, it facilitates the formation of peptide bonds between amino acids. It is particularly effective in solid-phase peptide synthesis, where it helps in the stepwise assembly of peptides. Additionally, it is employed in the synthesis of complex organic molecules, where it acts as a condensing agent to promote the formation of amide bonds. Its stability and reactivity make it a valuable tool in organic chemistry laboratories for the preparation of peptides and other amide-containing compounds.
