| | 4-Methylbenzenesulfonhydrazide Usage And Synthesis |
| Uses | p-Toluenesulfonyl Hydrazide is a reactant that has been used in the synthesis of paspaline. | | Chemical Properties | white to off-white powder | | Uses | p-Toluenesulfonyl hydrazide is used as a reagent for the preparation of tosylhydrazones. It was used to prepare dipyrazolo[1,5-a:4?,3?-c]pyridines and 1,2,3-selenadiazole derivatives. | | Uses | 4-Methylbenzenesulfonhydrazide was widely used reagent for the preparation of tosylhydrazones. | | Flammability and Explosibility | Not classified | | Purification Methods | Dissolve 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.] |
