This chemical is widely used in the field of bioconjugation and drug delivery due to its polyethylene glycol (PEG) chains, which enhance solubility and reduce immunogenicity. It serves as a linker molecule for attaching drugs, proteins, or other bioactive molecules, improving their stability and circulation time in the body. Its structure allows for the creation of multi-functional conjugates, making it valuable in targeted therapy and diagnostic applications. Additionally, it is utilized in the development of hydrogels and other biomaterials for tissue engineering and regenerative medicine. The dual PEG3-amine groups provide reactive sites for further functionalization, enabling customization for specific research or therapeutic needs.
