4-Methylbenzenesulfonhydrazide Usage And Synthesis
  • Usesp-Toluenesulfonyl Hydrazide is a reactant that has been used in the synthesis of paspaline.
  • Chemical Propertieswhite to off-white powder
  • Uses4-Methylbenzenesulfonhydrazide was widely used reagent for the preparation of tosylhydrazones.
  • Purification MethodsDissolve the hydrazide in hot MeOH (~1g/4mL), filter through Celite and precipitate the material by adding 2-2.5 volumes of distilled H2O. Dry it in air or in a vacuum. [Fiedman et al. Org Synth Coll Vol V 1055 1973, Beilstein 11 II 66.]
