SiliaBond®- Scavengers
SiliCycle offers a wide range of scavengers to simplify your purifications.
Scavengers are functionalized silica gels designed to react and bind excess reagents, metal complexes and/or by-products.More Information
The process for using scavengers is outlined in the scheme shown below. In the case of batch processing, the scavenger is added to the reaction mixture after completion. The process relies on chemically driven reactions where the excess reagents and reaction by-products react with and bind to the scavenger. The solution, which now only contains the product of interest, is separated from the silica bound impurities by filtration.
For flow through processing, the scavenger is packed into a column and the reaction mixture is passed through the column until complete scavenging is obtained.

SiliaBond® Amine
SiliaBond® Amine (Si-NH2) is an effective scavenger of acid chlorides, sulfonyl chlorides, isocyanates and other electrophiles. Si-NH2 has been shown to be effective metal scavenger and catalyst for Knoevenagel reactions. SiliaBond Amine is also used in chromatography as normal phase sorbent.

SiliaPrep™ SPE Cartridges Amine (WAX)
SiliaPrep Amine is a weak anion exchanger sorbent used in replacement of SAX for strong anions to avoid irreversible retention. Can also be employed as a metal scavenger and norman phase conditions.
-
SiliaPrep™ SPE Cartridges Amine nec (WAX)
SiliaPrep Amine nec is a weak anion exchanger sorbent used in replacement of SAX for strong anions to avoid irreversible retention. Can also be employed as a metal scavenger and norman phase conditions.
