This compound is widely utilized in the pharmaceutical and biotechnology industries as a linker or spacer molecule in drug delivery systems. Its polyethylene glycol (PEG) chains enhance solubility and stability, making it ideal for conjugating therapeutic agents, such as proteins, peptides, or small molecules, to improve their pharmacokinetic properties. It is also employed in the development of hydrogels and biomaterials, where its biocompatibility and ability to modify surface properties are highly valued. Additionally, it finds use in diagnostic applications, such as in the preparation of contrast agents or fluorescent probes, due to its ability to reduce immunogenicity and prolong circulation time in the body.
