Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its structure allows for selective functionalization, making it valuable in creating pyrimidine-based drug candidates. Also employed in agrochemical research for designing novel pesticides and herbicides due to its ability to interact with biological targets in pests and weeds. Additionally, it serves as a building block in the preparation of fluorescent dyes and optical brighteners used in imaging and material sciences.
