CAS 99479-46-6: 1H-Pyrazole-4-carboxylicacid, 5-amino-1-[2,6-dichloro-4-(trifluoromethyl)phenyl]-, ethyl ester

5-Amino-1-(4-chloro-2-ethoxy-6-fluorophenyl)-1H-pyrazole-3-carbonitrile is a crosslinking agent that can be used in polyurethane coatings, polyester resins and polyethylene. It is a white powder which is soluble in organic solvents such as acetone or toluene. This compound has been shown to be an effective crosslinker for epoxy resin. The reaction between 5-amino 1-(4-chloro 2 ethoxy 6 fluorophenyl)-1H pyrazole 3 carbonitrile and the epoxy resin results in an increase in tensile strength, elongation at break, and flexural modulus of the coating.
