N-α-Benzyl-glycine methyl ester hydrochloride is a glycine-based amino acid methyl ester bearing an N-α benzyl substituent, classifying it as a derivatized amino acid hydrochloride rather than a free amino acid. The molecule contains a methyl ester at the carboxyl terminus and a benzyl-protected amino function, with the hydrochloride salt form providing chloride counterion association to the protonated nitrogen. It is used as a protected amino acid building block for peptide and amide bond construction in solution-phase or solid-phase synthesis, where the ester and N-benzyl group help control chemoselectivity during stepwise assembly of more complex amino acid derivatives.
CAT No: CP00906
N-α-Benzyl-glycine methyl ester hydrochloride is a glycine-derived amino acid ester in which the α-amino group is protected as an N-benzyl substituent and the carboxyl functionality is present as a methyl ester, with the overall salt form provided by hydrochloride. The molecule therefore combines a chiral amino acid framework at the α-position with a benzylic stereochemical handle and an ester carbonyl that participates in standard amide-forming chemistry after activation. The benzyl group on nitrogen provides a stable protecting-group motif for peptide coupling compatibility, while the ester can be converted to amides or further functionalized to generate downstream protected amino acid derivatives. The hydrochloride salt improves handling of the amine during synthesis and supports reproducible incorporation into peptide-building sequences and chiral intermediate workflows.
1. Protected Amino Acid Coupling
N-α-Benzyl-glycine methyl ester hydrochloride is used in peptide synthesis workflows as an N-protected glycine ester building block compatible with amide bond formation strategies. The N-benzyl protection suppresses unselective reactions at the amino functionality, while the methyl ester can be transformed into an activated acyl equivalent for coupling to protected amino acids or peptide fragments. The α-amino acid backbone and ester carbonyl enable stepwise assembly of dipeptides and longer peptide chains under protecting-group orthogonality schemes. Downstream deprotection and ester conversion can furnish glycine-based peptide intermediates that retain stereochemical integrity throughout protected amino acid synthesis.
2. Chiral Intermediate Synthesis
N-α-Benzyl-glycine methyl ester hydrochloride serves as a chiral amino acid intermediate for stereocontrolled synthesis of substituted glycine derivatives and related chiral scaffolds. The α-stereocenter and N-benzyl substituent provide a defined three-dimensional arrangement that can be carried through subsequent transformations such as ester hydrolysis, amidation, or side-chain elaboration. The hydrochloride salt form supports reproducible handling in multistep routes where the amino functionality must remain protected until late-stage conversion. The resulting chiral intermediates can be applied to fine chemical synthesis and process chemistry intermediate preparation for downstream chiral building blocks.
3. Peptidomimetic Scaffold Construction
N-α-Benzyl-glycine methyl ester hydrochloride is applied in peptidomimetic construction where glycine-like backbone geometry and protected amine chemistry are required for scaffold diversification. The methyl ester and N-benzyl group allow controlled conversion into amide-linked motifs that mimic peptide bonds while enabling incorporation into larger molecular architectures. The ester functionality can be used as a handle for generating acyl derivatives that feed into heteroatom-containing linkers or constrained analogs, supporting structure-activity relationship studies in synthetic chemistry campaigns. The compound's protected amino acid character supports systematic derivatization toward non-natural peptide-like frameworks used in biochemical research tool development.
4. Chemical Biology Labeling Chemistry
N-α-Benzyl-glycine methyl ester hydrochloride can be incorporated into chemical biology labeling strategies that require a protected amino acid precursor for conjugation-ready derivatives. The N-benzyl protection and ester carbonyl enable conversion to functionalized amide or activated ester intermediates that can be coupled to biomolecule-reactive partners under protecting-group controlled conditions. The defined glycine backbone supports incorporation into short peptide tags, affinity handles, or linker segments used for molecular recognition experiments. The hydrochloride salt form facilitates consistent generation of reactive intermediates while preserving the stereochemical and functional-group layout needed for downstream biomolecule modification.
5. Pharmaceutical Intermediate Manufacturing
N-α-Benzyl-glycine methyl ester hydrochloride is suitable for pharmaceutical intermediate preparation and specialty chemical production where protected amino acid esters are used as feedstocks for controlled synthetic sequences. The N-benzyl protecting group is compatible with common peptide-coupling chemistries and can be removed when required to expose the free amine for subsequent functionalization steps. The methyl ester offers a manufacturable handle for transformation into amides or carboxylic acid derivatives during route design, supporting scalable intermediate generation. The compound's role as a chiral glycine-based building block aligns with industrial fine chemical synthesis practices that rely on protected amino acid chemistry and predictable downstream conversions.
