Solid-Supported Scavengers

We offer both polystyrene- and silica-supported scavengers. Removal of excess reagents and reaction byproducts with solid-supported scavengers simplifies product isolation immensely. The use of these products can eliminate exposure to problematic aqueous work-ups and significantly improve the efficiency of your important synthetic step.
