Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. It serves as a building block in the preparation of active pharmaceutical ingredients (APIs) due to its ability to form fused heterocyclic systems. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in drugs targeting inflammatory diseases and certain cancers. Also utilized in agrochemical research for designing novel pesticides and herbicides owing to its favorable hydrogen bonding and polarity characteristics.
