Used as an intermediate in peptide synthesis, particularly in the development of pharmaceutical compounds where steric hindrance and conformational restriction are important. The Boc (tert-butoxycarbonyl) group provides temporary protection of the amino group, allowing selective coupling reactions. The cyclopropylalanine moiety introduces a rigid structural element that can enhance metabolic stability and influence bioactivity. The dcha (dicyclohexylamine) salt form improves crystallinity and handling properties, making it suitable for purification and storage in multi-step syntheses. Commonly applied in research settings for designing enzyme inhibitors or receptor modulators.
