The invention discloses a color development test method for piperazine new psychoactive substances, and relates to the identification field of new psychoactive substances. This method uses Simon's reagent, vanillin reagent, Margarin's reagent and nitric acid-sulfuric acid reagent to carry out color reaction for known types of piperazine new psychoactive substances, and establishes a color development test screening program chart, and then According to the chromogenic inspection and screening procedure chart, the unknown species of piperazine new psychoactive substances to be detected were identified by using the four chromogenic reagents. The present invention establishes a color development test method for 22 kinds of piperazine new psychoactive substances. The method is simple and convenient, uses few reagents, does not need to use large-scale equipment and complicated instruments, and only needs to prepare 4 kinds of color-developing reagents (Siemen's reagent, Vanillin Reagent, Margarine Reagent and Nitric Acid-Sulfuric Acid Reagent), 22 new piperazine-type psychoactive substances can be rapidly tested on site by using test tubes, beakers, glass slides, white porcelain plates or thick white cardboards .
