Maleimide Chemical Properties,Uses,Production
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. [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.]
