mPEG-MAC is widely used in the field of bioconjugation and drug delivery due to its reactive methacrylate group, which allows for efficient coupling with various biomolecules. It is particularly valuable in creating PEGylated therapeutics, where it enhances the solubility, stability, and circulation time of drugs in the body. This chemical is also employed in the development of hydrogels and other biocompatible materials for tissue engineering and controlled release applications. Its ability to form covalent bonds with proteins, peptides, and other polymers makes it a versatile tool in modifying surfaces and improving the performance of biomedical devices. Additionally, mPEG-MAC is utilized in the synthesis of micelles and nanoparticles, which are critical for targeted drug delivery systems in cancer therapy and other medical treatments.
