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) targeting tyrosine kinase receptors. Also employed in the creation of agrochemicals and bioactive molecules due to its stable heterocyclic structure. Its chlorine functionality allows for further derivatization through cross-coupling reactions, making it valuable in medicinal chemistry and drug discovery research.
