This compound is primarily utilized in bioconjugation and chemical biology applications. It serves as a linker molecule for attaching biomolecules, such as peptides, proteins, or antibodies, to other entities like solid supports, dyes, or drugs. The T-Boc group provides protection for the aminooxy functionality during synthesis, which can later be deprotected for conjugation. The PEG2 spacer enhances solubility and reduces steric hindrance, making it ideal for creating stable and efficient conjugates. It is commonly used in drug delivery systems, diagnostic assays, and the development of targeted therapies.
