The invention discloses a method for controlling impurities in pipericide, and relates to the technical field of pharmaceutical chemical. The content of the impurities in the pipericide is reduced by controlling the purity of an obtained intermediate I. The content of a compound I in the intermediate I does not exceed 1.0%, the content of a compound II in the intermediate I does not exceed 5.0%, the content of a compound III in the intermediate I does not exceed 5.0%, the maximum single unknown impurity content does not exceed 2.0%, and the total impurity content does not exceed 9.0%. The method has the beneficial effect that main organic impurities can be effectively controlled by controlling the purity of the intermediate. The control method disclosed by the invention is simple and easy to realize, the product with higher purity and better quality is obtained, and the method is suitable for being applied to industrial production.
