6-Chloro-2,4-dimethoxypyrimidine serves as a key intermediate in pharmaceuticals, pesticides and fine chemical engineering. It is commonly used in the synthesis of sulfonylurea herbicides , and also applied to the preparation of pyrimidine ring-containing pharmaceutically active molecules. In addition, it acts as a heterocyclic building block to participate in the construction of pyrimidine derivatives, which is suitable for the research, development and production of functional molecules in organic synthesis and materials chemistry.
