This compound is primarily used in bioconjugation and protein modification processes. It serves as a reactive ester, enabling the attachment of various molecules, such as peptides, proteins, or drugs, to specific targets. Its structure includes a succinimidyl ester group, which reacts efficiently with primary amines, making it valuable for labeling, crosslinking, or functionalizing biomolecules. It is particularly useful in the development of antibody-drug conjugates (ADCs), where it helps link cytotoxic agents to antibodies for targeted cancer therapy. Additionally, it finds applications in creating bioconjugates for diagnostic imaging, drug delivery systems, and research tools in molecular biology. Its water-solubility and stability in aqueous solutions enhance its utility in biological and pharmaceutical contexts.
