Maleimide Usage And Synthesis
  • Chemical Propertiesslight yellow crystalline powder
  • UsesRhodium-catalyzed conjugate arylation with arylboronic acids.1
  • UsesReacts 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.
  • DefinitionChEBI: 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.
  • HazardA poison.
  • Safety ProfilePoison by intraperitoneal and intravenous routes. An experimental teratogen. Experimental reproductive effects. When heated to decomposition it emits toxic fumes of NOx.
  • Purification MethodsPurify it by sublimation in a vacuum. The UV has max at 216 and 280nm in EtOH. [de Wolf & van de Straete Bull Soc Chim Belg 44 288 1935, UV: Rondestvedt et al. J Am Chem Soc 78 6115 1956, IR: Chiorboli & Mirone Ann Chim (Rome) 42 681 1952, Beilstein 21/10 V 3.]
