Abstract: This article used thiosemicarbazide and para-pyridinecarboxylic acid to carry out reaction and synthesized 5-(4-pyridyl)-2-amino-1,3,4-thiadiazole, and then reacted with benzoyl isocyanate to synthesize a new type of urea biological active meterial. The structure of the target compound was confirmed by IR, 1H NMR and elemental analysis. The preliminarily biological activity tests show that the target compound has an activity as plant growth regulator, it’s activity as auxin is 19.3% and it’s activity as cytokinin is 27.4%.
