This chemical is primarily used in bioconjugation and crosslinking applications. It serves as a versatile linker for connecting biomolecules, such as proteins, peptides, or antibodies, due to its aldehyde functional groups. These groups react with amine-containing compounds, enabling the formation of stable covalent bonds. It is particularly useful in the development of antibody-drug conjugates (ADCs), where it helps attach therapeutic agents to antibodies for targeted drug delivery. Additionally, its PEG (polyethylene glycol) spacer enhances solubility and reduces steric hindrance, improving the efficiency of conjugation processes. This compound is also employed in material science for surface modification and in the synthesis of hydrogels for biomedical applications.
