Pharmaceutical Intermediate
tert-Butoxycarbonyl-L-leucine (Boc-Leu-OH) is a derivative of the amino acid L-leucine, where the amino group is protected by a tert-butoxycarbonyl (Boc) group. It is widely used as a building block in solid-phase peptide synthesis, enabling the sequential assembly of peptides while preventing unwanted side reactions at the amine site.
