This chemical is widely used in bioconjugation and peptide synthesis due to its reactive NHS ester groups, which facilitate the coupling of molecules to amines. It is particularly valuable in creating PEGylated compounds, enhancing solubility, stability, and biocompatibility of biomolecules like proteins, peptides, and antibodies. Its application extends to drug delivery systems, where it helps in modifying therapeutic agents to improve pharmacokinetics and reduce immunogenicity. Additionally, it is employed in the development of bioconjugates for diagnostic imaging and targeted therapies, enabling precise delivery of active agents to specific tissues or cells. The Boc protecting group ensures selective deprotection during synthesis, allowing for controlled and efficient reactions.
