Used in the synthesis of drug delivery systems, this compound plays a key role in modifying biomolecules to enhance their solubility and stability. It is often employed in the creation of polyethylene glycol (PEG) conjugates, which are crucial for improving the pharmacokinetics of therapeutic proteins and peptides. Additionally, it serves as a linker in bioconjugation techniques, enabling the attachment of drugs or imaging agents to targeting molecules. Its application extends to the development of hydrogels and other biomaterials for tissue engineering and regenerative medicine.
