Used extensively in organic synthesis as a highly effective coupling reagent, particularly in peptide bond formation. It facilitates the condensation of amino acids, enabling the production of peptides and proteins with high efficiency and minimal racemization. Additionally, it is employed in the synthesis of complex organic molecules, including pharmaceuticals, due to its ability to activate carboxylic acids and promote amide bond formation. Its stability and reactivity make it a preferred choice in solid-phase peptide synthesis and other advanced chemical transformations.
