4- (Maleimido) benzophenone

4- (Maleimido) benzophenone is a biochemical reagent.The molecule simultaneously contains an active maleimide group and a benzophenone aromatic ring structure. The maleimide group can specifically undergo addition reactions with the thiol group (-SH) in biological macromolecules, while the benzophenone structure endows it with certain photoreactivity, thus giving it bifunctional properties.
