This methyl ester of Boc-L-pyroglutamic acid is a cyclic amino acid derivative commonly used in the synthesis of peptide fragments and chiral intermediates. The combination of a Boc-protected nitrogen and a methylated carboxyl end improves solubility and enables smooth integration into ester-based coupling reactions.
