This chemical is widely used in bioconjugation and drug delivery systems due to its amphiphilic nature and biocompatibility. The Boc group serves as a protective group for amines, allowing selective reactions in peptide synthesis. The PEG (polyethylene glycol) spacer enhances solubility, reduces immunogenicity, and improves the pharmacokinetics of conjugated molecules. The terminal amine group enables covalent attachment to various biomolecules, such as proteins, peptides, or drugs, facilitating targeted delivery or surface modification. It is commonly employed in the development of antibody-drug conjugates (ADCs), PEGylated therapeutics, and functionalized nanoparticles for biomedical applications. Additionally, it is used in the synthesis of hydrogels and biomaterials for tissue engineering and controlled drug release systems.
