Used as a key intermediate in the synthesis of antiviral and antitumor agents, particularly in the development of nucleoside analogs. Its structure allows for modification at multiple sites, making it valuable in medicinal chemistry for designing inhibitors targeting RNA and DNA viruses. Commonly employed in the preparation of kinase inhibitors and other bioactive molecules due to its ability to mimic pyridone scaffolds found in natural compounds. Also utilized in agrochemical research for developing novel pesticides with improved selectivity and lower toxicity.
