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 in solid-phase peptide synthesis, enabling the production of complex peptides with high yield and purity. Additionally, it is employed in organic synthesis for activating carboxylic acids, making it useful in the preparation of esters, amides, and other derivatives. Its stability and reactivity under mild conditions make it a preferred choice in laboratories and industrial settings for constructing sensitive and intricate molecules.
