| SP – TRISAMINE - SILICA |
|
PRODUCT: |
| SP-Trisamine-Silica, a trisamine-functionalized silica gel |
| |
| APPLICATIONS: |
- SP-Trisamine-Silica has a silica supported polyamine functional group.
- Highly effective in scavenging metals such as Pd, Ru, Pb and Co.
- Can be also used for scavenging of excess electrophilic reagents, such as acid chlorides, sulfonyl chlorides, and isocyanates during the quenching and purification of reaction mixtures.
- SP-Trisamine-Silica may also be used as a weak anion exchanger, and is the closest silica equivalent of polyethyleneimine.
- Compatible with a broad range of solvents including DMF and acetonitrile.
