Allgemeine Beschreibung
3-Amino-5-phenylpyrazole (3-phenyl-1H-pyrazol-5-amine), an amino pyrazole derivative, is an aza-heterocyclic amine. It has been reported to be synthesized by heating either 3-amino-4-bromo- or 3-amino-5-phenylisothiazole in the presence of anhydrous hydrazine. On reaction with ZnCl2 it affords chlorido-tris(3-amino-5-phenyl-1Hpyrazole-N2)zinc (II) chloride.
