This chemical is primarily used in bioconjugation and protein labeling applications. It serves as a reagent for introducing aminooxy functional groups into biomolecules, enabling the formation of stable oxime bonds with carbonyl-containing compounds like aldehydes and ketones. This property is particularly useful in modifying peptides, proteins, and antibodies for research, diagnostics, and therapeutic purposes. It is also employed in the synthesis of immunoconjugates and drug delivery systems, where precise attachment of functional groups is critical. Additionally, it facilitates the study of protein-protein interactions and the development of targeted therapies by allowing site-specific modifications. Its tert-butoxycarbonyl (Boc) protecting group ensures selective reactivity, making it a valuable tool in organic synthesis and bioconjugation strategies.
