Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of certain antiviral and anticancer agents. Its structure allows for selective functionalization, making it valuable in building active pharmaceutical ingredients (APIs) that target specific enzymes or receptors. Commonly employed in the development of kinase inhibitors due to its ability to mimic purine bases in biological systems. Also utilized in agrochemicals for the creation of herbicides and plant growth regulators, where its chloro and methoxy groups facilitate optimal binding and stability.
