Sigma-Aldrich launches ChemDose compound handling technology

Sigma-Aldrich has launched ChemDose, a novel compound handling technology designed to enable easy delivery of reagents and catalysts in tablet form.

Co-developed with Reaxa, ChemDose 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, minimise waste and are compatible with microwaves, parallel synthesis equipment, and non-aqueous and aqueous solvents. Reaction kinetics utilising ChemDose closely parallel the corresponding conventional reagent under the same conditions. Additionally, ChemDose tablets minimise exposure and offer convenient handling of difficult-to-use chemicals.

Currently available ChemDose products include common palladium catalysts, ligands for cross-coupling, and peptide coupling reagents.
