Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides and fungicides. Its structure allows for easy functionalization, making it valuable in creating active ingredients that target specific enzymes in pests or pathogens. Also employed in the preparation of pyrimidine-based drug candidates due to its electron-deficient ring system, which enhances binding to biological targets. Commonly utilized in cross-coupling reactions to build complex molecules in medicinal chemistry research.
