Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of biologically active compounds where stereochemistry plays a critical role. Its strained azetidine ring and nitrile functionality make it valuable for constructing complex molecules in medicinal chemistry. Commonly employed in the preparation of enzyme inhibitors and receptor modulators, especially in central nervous system and metabolic disorder drug research. The oxalate salt form enhances stability and crystallinity, facilitating handling and purification during synthetic processes.
