This chemical is widely used in bioconjugation and drug delivery systems due to its polyethylene glycol (PEG) chains, which enhance solubility and stability of compounds. It is often employed to modify proteins, peptides, and other biomolecules, improving their pharmacokinetics and reducing immunogenicity. The compound is also utilized in the development of targeted therapies, where its structure allows for controlled release and efficient delivery of active pharmaceutical ingredients to specific tissues or cells. Additionally, it plays a role in nanotechnology applications, such as the creation of PEGylated nanoparticles for enhanced drug delivery and diagnostic purposes.
