Application

1,2-Diethylhydrazine dihydrochloride was used in the synthesis of 4,5-dihydro-pyrazole, pyrazolidine and 1,2-dihydro-phthalazine derivatives.
Reactant involved in:
  • Bromopyridazinedione-mediated protein and peptide bioconjugation
  • Synthesis of human neutrophil proteinase 3 inhibitors
  • Three-component cascade processes for sythesis of aminoisoindolones and phthalazones
  • Stereoselective heterocyclization for synthesis of substituted hexahydropyrazolodiazepinecarboxylates
  • Synthesis of azacycloalkanes, isoindoles, pyrazole, pyrazolidine, and phthalazine derivatives
