This chemical is widely used in the field of bioconjugation and drug delivery systems. It serves as a linker molecule, enabling the attachment of bioactive molecules to various carriers or surfaces. Its PEG (polyethylene glycol) spacer enhances solubility and reduces immunogenicity, making it ideal for creating biocompatible conjugates. The T-Boc protecting group allows for controlled deprotection during synthesis, ensuring precise chemical modifications. It is particularly valuable in the development of targeted therapies, antibody-drug conjugates, and peptide-based pharmaceuticals, where stability and controlled release are critical. Additionally, it finds applications in the preparation of hydrogels and other biomaterials for tissue engineering and regenerative medicine.
