This compound is widely used in bioconjugation and click chemistry applications. It serves as a linker or spacer in the synthesis of complex molecules, particularly in drug delivery systems and bioconjugate chemistry. The Boc group provides protection for the amine functionality during synthesis, while the azide group allows for efficient click reactions, such as with alkynes, to form stable triazole linkages. Its PEG7 chain offers solubility, flexibility, and biocompatibility, making it suitable for modifying peptides, proteins, and other biomolecules. It is particularly valuable in designing targeted therapeutics, diagnostic probes, and materials for biomedical research.
