Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its ability to form stable heterocyclic structures that interact with biological targets. Commonly employed in the preparation of small-molecule drugs targeting inflammatory diseases and neurological disorders. Its chloro and carboxamide functional groups allow for further chemical modifications, making it valuable in structure-activity relationship studies during drug discovery. Also utilized in agrochemical research for designing new pesticides with improved selectivity and efficacy.
