Catonium mtpb - Phase Transfer Catalysts

Catonium MTPB (Methyltriphenylphosphonium Bromide) is white powder, its chemical formula is C19H18BrP. MTPB is a quaternary phosphonium salt mainly used in organic synthesis as a wittig reagent and as a phase transfer catalyst in the production of Powder Coatings. This material is highly soluble in water and polarizable solvents. Methyltriphenylphosphonium Bromide is also known as MTPB, Triphenyl phosphate bromide and triphenylmethylphosphonium. Compared to amines, imidazoles and quaternary ammonium salts CatOnium MTPB features considerable better latency and thermal stability. Further it offers a low odor, minimal color formation and controlled reactivity.
