(1R,3S)-3-(Carbobenzoxyamino)cyclohexanecarboxylic Acid is a chiral building block and protected amino acid derivative used primarily in peptide and organic synthesis. The carbobenzoxy (Cbz) group protects the amino functionality on the cyclohexane ring, enabling selective activation and coupling of the carboxylic acid group to form peptide bonds or amide linkages without interference from the amine. Its rigid cyclic structure and defined stereochemistry (1R,3S) are particularly valuable for synthesizing conformationally constrained, enantiomerically pure compounds in pharmaceutical research and the development of bioactive molecules with specific biological activities.
