    Patent number: 10870620
    Abstract: The present disclosure provides a radioactive carbon-14 labeled XCLSBM in the structure of Formula 4 and its preparation method and applications. A 14C labeled raw material is used to synthesize a 14C-labeled XCLSBM, and a method for synthesizing a trace 14C-labeled marker of 14C-labeled XCLSBM is established, which avoids high-temperature, high-pressure reactions and the production process is safe with a low synthesis cost. The radioactive carbon-14 labeled XCLSBM can be used to trace the migration and transformation, metabolic degradation, absorption and enrichment of XCLSBM in environment and living bodies, for providing technical supports for comprehensive evaluation of the ecological safety of XCLSBM.
