| SP - THIOUREA RESIN, MP |
| PRODUCT: |
| SP-Thiourea Resin, MP, a highly cross-linked polystyrene resin functionalized with a Thiourea end group |
| |
| APPLICATIONS: |
- SP-Thiourea Resin is a polymer bound thoiurea.
- It is designed to provide strong interactions with a variety of heavy metal species.
- It is highly effective in scavenging of all forms of palladium.
- It can be also used for scavenging of metals like platinum, ruthenium, tin, mercury, nickel, copper.
- Other uses for these compounds have also been reported, including hydrogenolysis of endoperoxides.
- There also remains the possibility of using these polymer supported reagents as co-catalysts in some metal mediated reactions.
- Polymer supported Thiourea bound transition metals have been reported as effective catalysts for organic synthesis.
- It is compatible in both aqueous and non aqueous solutions.
