Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of biologically active compounds targeting central nervous system disorders and metabolic diseases. Its azetidine core with a fluoromethyl group enhances metabolic stability and membrane permeability, making it valuable in medicinal chemistry for optimizing drug candidates. Commonly employed in the preparation of enzyme inhibitors and receptor modulators where fluorine substitution improves binding affinity and pharmacokinetic profiles.
