N,N' Methylenebisacrylamide

N,N'-Methylenebisacrylamide (MBAm or MBAA) is a cross-linking agent used during the formation of polymers such as polyacrylamide. Its molecular formula is C₇H₁₀N₂O₂. Bisacrylamide is used in biochemistry as it is one of the compounds of the polyacrylamide gel (used for SDS-PAGE). Bisacrylamide polymerizes with acrylamide and is capable of creating cross-links between polyacrylamide chains, thus creating a network of polyacrylamide rather than unconnected linear chains of polyacrylamide.
