摘要：Derivatives of nitrogen-containing heterocycles, in particular compounds of symmetric and asymmetric triazines, are widely used in agriculture as regulators of plant growth and development. Among the derivatives, the most well-known use of symmetric derivatives, however, they are difficult to biodegrade and accumulate in the soil, and as a result in the plants themselves. Therefore, asymmetric triazines, which are easily decomposed in the environment, are more promising in practical terms. Currently, it is very important to use environmentally friendly plant growth and development regulators that do not contain impurities, so much attention is paid to the identification of synthesized compounds of asymmetric triazines with a substituent in position 5 using UV, IR and Mass spectroscopy.
