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 heterocyclic structure, enabling coupling reactions in drug design. Also employed in agrochemicals for the creation of novel pesticides with improved efficacy. Its chloro group allows for easy functionalization, making it valuable in combinatorial chemistry and medicinal research.
