TCI B6364, Z-Asp(OtBu)-OH (CAS 5545-52-8), is a doubly protected aspartic acid derivative bearing a benzyloxycarbonyl group on the amino function and a tert-butyl ester on the side-chain carboxyl. This orthogonal arrangement lets chemists remove each protecting group under different conditions — hydrogenolysis for the Z group and acid for the tert-butyl ester — giving precise control over each synthetic step. Keeping the side chain masked helps suppress unwanted cyclisation and branching at aspartate residues during chain elongation. AMI Scientific supplies this TCI peptide-chemistry reagent in 5 g and 25 g pack sizes for research use.
