June 19, 2007 — /PRNewswire-FirstCall/ — ST. LOUIS, MO — Sigma-Aldrich is pleased to launch ChemDose(TM), a novel compound handling technology designed to enable easy delivery of reagents and catalysts in tablet form.
ChemDose, co-developed with Reaxa, Ltd., involves absorption of reagents into an inert tablet matrix. On exposure to solvents, the reagents readily dissolve out, leaving behind an easily removed insoluble tablet. ChemDose tablets offer the timesaving convenience of pre-weighed reagents, minimize waste, and are compatible with microwaves, parallel synthesis equipment, non-aqueous and aqueous solvents. Reaction kinetics utilizing ChemDose closely parallel the corresponding conventional reagent under the same conditions. Additionally, ChemDose tablets minimize exposure and offer convenient handling of difficult-to-use chemicals.
“ChemDose is another way to accelerate the success of our customers, and we look forward to expanding the ChemDose offering through customer feedback,” says Charles Davis, technology transfer manager, chemistry, Sigma-Aldrich.
Currently available ChemDose products include common palladium catalysts, ligands for cross-coupling, and peptide coupling reagents. To learn more about technical and application information, please visit http://sigma-aldrich.com/chemdose.
