General description

1,2-Diphenylhydrazine is mainly used in the manufacture of fabrics and medicines. Its other applications include, but not limited to: a precursor of benzidine, an antisludging additive for motor oil, a constituent in photochromic resins as well as in polymers, and syntheses of hydrogen peroxide (H2O2) and several dyestuffs.

Application

1,2-Diphenylhydrazine may be used as an analytical standard for the determination of the analyte in landfill leachate, pharmaceutical process stream, and aqueous solutions by high-performance liquid chromatography (HPLC) and gas chromatography (GC) based analytical techniques.
Reactant involved in:
  • Insertion reactions with organometallic tantalum complexes
  • Reduction reactions catalyzed by titanium(III) trichloride yielding amines
  • Studying the mechanism of hydrazobenzene rearrangement
  • Reaction with N-heterocyclic stable silylene
  • Synthesis of dimanganese amide hydrazide cluster complexes
  • Iron-mediated hydrazine reductions yielding iron arylimide cubanes
