用红外光谱法、核磁共振法、质谱法等方法对经三年时间人工合成的二苯脲进行的鉴定研究，以及应用情况表明，二苯脲不仅具有嘌呤类植物生长调节剂的作用，且生产成本大大低于后者，故而具有广阔的应用前景。
The identification of diphenyl urea synthesized by three years and its application by infrared spectroscopy, nuclear magnetic resonance and mass spectrometry showed that diphenyl urea not only possesses purine plant growth regulator but also produces The cost is much lower than the latter, so it has a broad application prospects.
