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

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

Alginic acid is a suitable material for modification to prepare new derivatives because of presence of its carboxyl groups. The high content of carboxyl groups over the entire length of its chain renders it an easily modifiable material with a

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
