Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its structure allows for easy functionalization, making it valuable in creating active pharmaceutical ingredients (APIs) that target specific enzymes or receptors. Commonly employed in agrochemicals as well, especially in the production of herbicides and fungicides due to its ability to enhance bioactivity. Also utilized in research laboratories for building more complex heterocyclic compounds in medicinal chemistry.
