Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and fungicides, due to its reactive pyrimidine ring and halogen substituents that facilitate further chemical modifications. Its structure allows for selective substitution reactions, making it valuable in developing active ingredients with targeted biological activity. Also employed in the preparation of pharmaceutical compounds, especially in the construction of heterocyclic systems found in certain kinase inhibitors and antimicrobial agents. Commonly utilized in research and development for creating novel compounds in medicinal and agricultural chemistry.
