Used in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) that require trifluoromethyl groups for enhanced biological activity. It serves as a building block in organic chemistry for creating compounds with potential therapeutic applications, such as enzyme inhibitors or receptor modulators. The trifluoromethyl group imparts unique properties like metabolic stability and lipophilicity, making it valuable in drug design. Additionally, it is employed in research for studying the effects of fluorine substitution on molecular interactions and drug efficacy. Its hydrochloride form ensures better solubility and handling in various chemical reactions.
