Used primarily as a fluorinating and acylating agent in organic synthesis, enabling the introduction of fluorinated groups into complex molecules. Its reactivity makes it valuable in pharmaceutical manufacturing, particularly in the development of fluorinated analogs with enhanced metabolic stability. It is also employed in the synthesis of agrochemicals and specialty materials where fluorine substitution improves performance. Due to its high reactivity, it is handled under controlled conditions, often in anhydrous environments and with inert atmosphere protection.
