Maleimide (CAS: 541-59-3) is an organic compound with the chemical formula C4H3NO2. It belongs to the family of cyclic imides. It has a cyclic unsaturated four-membered ring with a carbonyl group attached to two imide nitrogen atoms.
Maleimide is involved in Rhodium-catalyzed conjugate arylation with arylboronic acids. Maleimide is actively involved in Michael additions and Diels-Alder reactions by the addition across the double bond. Maleimide acts as crosslinking reagents in polymer chemistry.
Maleimide is also used in the development of new pharmaceuticals and materials for medical and industrial use. Maleimide is a highly reactive compound that has a wide range of applications in biochemistry, biotechnology, pharmaceuticals, protein modification, cross-linking, labeling, and drug development. Maleimide can also be used in the synthesis of various polymers, bioconjugates, materials science, and analytical chemistry.
Maleimide can also be used to modify proteins for use in immunoassays and to attach DNA or other nucleic acid molecules to surfaces for use in DNA sequencing and other molecular biology techniques. Finally, Maleimide can be used to create novel materials for use in nanotechnology and other advanced technologies.
