N-Benzyloxycarbonyl-L-alanine (CAT: R043489) is a protected amino acid derivative in which the α-amino group of L-alanine is blocked by a benzyloxycarbonyl (Cbz or Z) group. This protecting group is widely used in peptide synthesis, offering stability under basic and mildly acidic conditions, and can be removed via hydrogenolysis. Z-L-alanine preserves the natural L-stereochemistry and is a versatile building block for stepwise solution-phase or solid-phase peptide assembly. It is frequently used in the preparation of peptides, peptidomimetics, and enzyme substrates.
