Phase Transfer Catalysts

Our phase transfer catalyst range covers the quaternary ammonium and phosphonium salts used to carry reactants between aqueous and organic phases — in alkylation, substitution and condensation chemistry for pharmaceutical, agrochemical and fine chemical manufacture — along with triphenyl phosphonium salts used as Wittig reagent precursors and curing accelerators. Share the assay, moisture limit and packing you work to and we will respond with availability and a quotation.
