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 bioactive molecules due to the presence of both amine and trifluoromethylpyridine functionalities, which enhance binding affinity and metabolic stability. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in drugs targeting inflammatory diseases and oncology. Its hydrochloride salt form improves solubility and handling in aqueous reaction conditions.
