Used as a key intermediate in the synthesis of pharmaceutical compounds, 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 active pharmaceutical ingredients (APIs) for investigational drugs targeting inflammatory diseases and neurological disorders. Its amino and chloro functional groups allow for selective derivatization, enabling structure-activity relationship (SAR) studies during drug optimization. Also utilized in agrochemical research for designing bioactive molecules with pesticidal or herbicidal properties.
