This chemical is primarily used as a coupling reagent in peptide synthesis. It facilitates the formation of amide bonds between amino acids, making it valuable in the production of peptides and proteins. Its high reactivity and efficiency ensure minimal racemization, which is crucial for maintaining the stereochemical integrity of the synthesized peptides. Additionally, it is employed in bioconjugation processes, where it links biomolecules like proteins or antibodies to other molecules, such as fluorescent dyes or drugs, for various research and diagnostic applications. Its stability and solubility in organic solvents further enhance its utility in laboratory settings.
