Used in bioconjugation and drug delivery systems to improve solubility and stability of therapeutic agents. Acts as a linker in the development of antibody-drug conjugates (ADCs) for targeted cancer therapy. Enhances the pharmacokinetic properties of drugs by increasing their circulation time in the body. Applied in surface modification of nanoparticles for biomedical applications. Utilized in peptide and protein modification to improve their functionality and reduce immunogenicity. Plays a role in the synthesis of hydrogels for controlled drug release. Employed in the preparation of PEGylated compounds to minimize aggregation and enhance bioavailability.
