Applications
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.

Solubility
Soluble in water.

Notes
Store in a cool place. Incompatible with strong oxidizing agents, strong acids, strong bases and strong reducing agents.
