Description générale
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.

The sequential use of Cu-catalyzed asymmetric allylic alkylation, olefin cross-metathesis, and Ir-catalyzed asymmetric allylic amination allows the concise, stereodivergent synthesis of complex chiral amines with complete regiocontrol and good diastereoselectivity, exemplified by the synthesis of a pair of diastereoisomeric unnatural
