Used in bioconjugation and crosslinking applications, it serves as a linker molecule to connect biomolecules like proteins, peptides, or antibodies. Its PEG (polyethylene glycol) spacer enhances solubility and reduces steric hindrance, improving the efficiency of conjugation processes. Commonly employed in drug delivery systems, it helps create stable and targeted therapeutic agents. Also utilized in the development of diagnostic tools and research reagents, enabling precise labeling and detection of biomolecules. Its trifunctional structure allows for versatile modifications in chemical synthesis.
