Used primarily as an intermediate in organic synthesis, especially in the pharmaceutical industry. It serves as a building block for fluorinated compounds, which often exhibit enhanced metabolic stability and bioavailability. Commonly employed in the development of active pharmaceutical ingredients (APIs) where fluorine substitution improves drug performance. Also utilized in the preparation of specialty amides and peptides, supporting research in medicinal chemistry and drug design. Its reactivity allows for efficient incorporation into complex molecules under mild conditions.
