This chemical is widely used 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 drugs, proteins, or peptides to improve their pharmacokinetic properties. It is also utilized in the development of hydrogels and biomaterials for controlled release applications. Additionally, its hydrophilic nature makes it suitable for modifying surfaces to reduce protein adsorption and improve biocompatibility in medical devices. In research, it serves as a versatile tool for studying molecular interactions and designing targeted therapies.
