This chemical is primarily used in the field of bioconjugation and drug delivery systems. It serves as a versatile linker or spacer molecule, enabling the attachment of bioactive molecules to polymers, nanoparticles, or other carriers. Its PEG (polyethylene glycol) moiety enhances solubility and reduces immunogenicity, making it suitable for improving the pharmacokinetics of therapeutic agents. The Boc (tert-butoxycarbonyl) protecting group allows for controlled deprotection, facilitating precise chemical modifications. It is particularly valuable in the development of targeted therapies, such as antibody-drug conjugates (ADCs), where it helps maintain the stability and functionality of the conjugated molecules. Additionally, it finds applications in peptide synthesis and the creation of functionalized biomaterials for tissue engineering.
