|  |  | Maleimide Usage And Synthesis | 
 | Chemical Properties | slight yellow crystalline powder |  | Uses | Rhodium-catalyzed conjugate arylation with arylboronic acids.1 |  | Uses | Reacts quantitatively with sulfhydryl groups.Maleimide is used to immobilize the bovine serum albumin-boronic acid conjugates in association with silica beads. Its nanoparticle surface favors the conjugation with cell penetration peptides. It is involved in Rhodium-catalyzed conjugate arylation with arylboronic acids. It is actively involved in Michael additions and Diels-Alder reactions by the addition across the double bond. It acts as crosslinking reagents in polymer chemistry. |  | Definition | ChEBI: A cyclic dicarboximide in which the two carboacyl groups on nitrogen together with the nitogen itself form a 1H-pyrrole-2,5-dione structure. |  | General Description | Maleimide (2,5-Pyrroledione) is a new nanoparticle surface functional group which favors easy conjugation with cell penetration peptides. The conjugation is enabled via click chemistry to preserve its biofunctions. |  | Hazard | A poison. |  | Safety Profile | Poison by 
intraperitoneal and intravenous routes. An 
experimental teratogen. Experimental 
reproductive effects. When heated to 
decomposition it emits toxic fumes of NOx. |  | Purification Methods | Purify it by sublimation in a vacuum. The UV has max at 216 and 280nm in EtOH.
