General description
QuadraPure® TU is a thiourea-based metal scavenger resin that can be used to prevent metal contamination that occurs during pharmaceutical or fine chemical processing.
Application
Metal Scavenger: Pd, Pt, Ru, Rh, Au, Ag, Cu, Hg, Pb, Cd, Ni, Co, Fe, V, Zn
QuadraPure® TU has been used to remove color from the solution due to leaching of copper species during the copper(I)-mediated 1,2,3-triazole formation via [3+2] cycloaddition of acetylenic compounds with azides. It has also been used as a modifier for carbon pastes to develop QuadraPure® TU residue functionalized resin-modified carbon paste electrode (“TUR-CPE”) for the determination of Pb(II) ions.
Other applications include the removal of metal ions like copper and palladium that leach out during continuous flow coupling reactions.
