16. Use Of SiliaBond® Cysteine
SiliaBond® Cysteine (Si-Cys) is the silica bound equivalent of the amino acid Cysteine. By attaching the molecule to the backbone via the amino group, the thiol group remains free and accessible for higher metal scavenging efficiency. It is a versatile metal scavenger for a variety of metals including Pd, Sn, Ru, Pt, Cu, Rh, Cd and Sc under a wide range of conditions and the preferred metal scavenger for tin residues.
Cysteine has been reported to efficiently remove palladium and heavy metals in aqueous solutions but its limited solubility in organic solvent can limit its range of applications. By using SiliaBondCysteine, solubility issues can be solved and almost all solvents can now be used.
