What is a supported scavenger?

> back to the scavengers FAQ page

A supported scavenger is a reactive functional group grafted onto a silica backbone.

Once a reaction is completed, a supported scavenger can be introduced in the reaction flask or the reaction solution can be passed through a SPE cartridge packed with the chosen scavenger. The scavenger will react with and bind excess reagent and/or by-products achieving a chemically driven separation. Purification is now a simple filtration and evaporation process.
