Product Application Of N,N-Dimethyl-p-toluidine CAS#99-97-8

N,N-Dimethyl-p-toluidine is used as a polymerization catalyst for polyesters, acrylate and epoxy resins. It is also used as a hardener for dental cements and in adhesives. It serves as an intermediate for photographic chemicals, in industrial glues, in artificial fingernail preparations, colorants, pharmaceuticals. It reacts with vinyl ether in the presence of copper(II) chloride gives tetrahydroquinolines. Further, it is used to accelerate polymerization of ethyl methacrylate.
