This chemical is primarily utilized in the field of bioconjugation and drug delivery systems. Its structure, featuring a tert-butyl ester and a polyether chain, makes it suitable for creating PEGylated compounds, which are often used to enhance the solubility, stability, and circulation time of therapeutic agents. The amino group allows for easy conjugation with various biomolecules, such as proteins, peptides, or drugs, enabling targeted delivery and improved pharmacokinetics. Additionally, it finds applications in the development of advanced materials, including hydrogels and coatings, where its amphiphilic nature can be leveraged to modify surface properties or create self-assembled structures.
