General description

Hydrazine monohydrochloride is commonly used as a reagent in the synthesis of pyrazoles.

Application

Hydrazine monohydrochloride has been used:
  • as catalyst in the synthesis of titanium oxide polymers via catalytic sol-gel process
  • in fabrication of amorphous titanium dioxide (TiO2) thin films exhibiting high refractive indices and high transparency
  • in preparation of ethyl 3-ethoxy-1H-pyrazole-4-carboxylate

Our program, which has focused on the preparation of new pyrazole derivatives, has led us to report here an original and simplified preparation of ethyl 3-ethoxy-1H-pyrazole-4-carboxylate. This is based on the reaction of hydrazine monohydrochloride and diethyl 2-(ethoxymethylene)malonate. Further transformations

Amorphous titanium dioxide (TiO(2)) thin films exhibiting high refractive indices (n ≈ 2.1) and high transparency were fabricated by spin-coating titanium oxide liquid precursors having a weakly branched polymeric structure. The precursor solution was prepared from titanium tetra-n-butoxide (TTBO) via
