TCI C0640 N-Carbobenzoxy-beta-alanine is the Cbz-protected derivative of beta-alanine, an amino acid whose three-carbon backbone introduces added conformational flexibility. It is widely employed as a flexible spacer that separates functional groups and relieves steric crowding within a target molecule. The protected amine can be liberated selectively by hydrogenolysis, while the free carboxylic acid is readily activated with standard coupling reagents. AMI Scientific offers this TCI product in 1 g and 10 g packs, covering both exploratory work and ongoing synthetic projects.
