This chemical is primarily used in bioconjugation and protein labeling applications. Its maleimide group allows for selective attachment to thiol groups in proteins, peptides, and other biomolecules, enabling the creation of stable covalent bonds. The benzophenone moiety is highly effective in photoaffinity labeling, where it can form covalent bonds with nearby molecules upon exposure to UV light. This makes it valuable in studying protein-protein interactions, mapping binding sites, and developing targeted drug delivery systems. Additionally, it is employed in the synthesis of polymer materials and surface modifications, where its dual functionality facilitates crosslinking and immobilization processes. Its versatility makes it a useful tool in biochemical research and material science.
