This chemical is primarily used in the field of bioconjugation and drug delivery. It serves as an activating agent for carboxylic acids, facilitating the formation of amide bonds with amines. This property makes it valuable in the synthesis of peptide and protein conjugates, where it helps link biomolecules to other entities such as drugs, polymers, or fluorescent tags. Additionally, it is employed in the development of prodrugs, where it aids in creating compounds that release active drugs in a controlled manner upon enzymatic action. Its application is particularly significant in targeted therapy and diagnostic imaging, enhancing the specificity and efficiency of therapeutic agents.
