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 the preparation of active pharmaceutical ingredients (APIs) due to its reactive amine and halogen groups, which allow for further functionalization. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in optimizing pyridine-based drug candidates. Also utilized in agrochemical research for designing novel pesticides with improved efficacy and selectivity.
