This chemical is widely used in bioconjugation and click chemistry applications. It serves as a linker molecule for attaching functional groups, such as aminooxy or propargyl, to biomolecules like proteins, peptides, or antibodies. The T-Boc protecting group ensures stability during synthesis, while the PEG6 spacer enhances solubility and reduces steric hindrance. It is particularly useful in developing antibody-drug conjugates (ADCs) and targeted drug delivery systems. Additionally, it plays a role in labeling biomolecules for imaging and diagnostic purposes, enabling precise tracking and analysis in biological studies.
