Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for building pyrimidine-based drug candidates. Commonly employed in the preparation of antitumor, antiviral, and anti-inflammatory agents. Also utilized in agrochemical research for designing new crop protection agents due to its reactivity and stability in various coupling reactions.
