(2s,3R)-3-Methylglutamic acid is a non-proteinogenic, side-chain-substituted amino acid belonging to the glutamic acid family, featuring a substituted 5-carbon backbone with a terminal carboxylic acid and an additional carboxylate side chain characteristic of glutamate-like structures. The molecule bears two carboxylic acid functional groups and one amino group, with stereochemical configuration indicated as (2s,3R) and a 3-methyl substituent that modulates side-chain sterics and polarity relative to unsubstituted glutamic acid. As a structurally defined glutamate analogue, it is used in peptide and amino acid derivative synthesis and in structure-activity or chemical biology studies where glutamate-like functionality and stereochemistry are required for controlled incorporation or analytical comparison.
CAT No: CP08204
(2s,3R)-3-Methylglutamic acid is a stereochemically defined glutamic acid derivative featuring a methyl-substituted side chain that preserves the key α-amino and α-carboxyl functionality while introducing a steric/electronic bias at the side-chain carbon. This non-proteinogenic amino acid is commonly handled as a free amino acid for chemical synthesis and as a building block for preparing constrained or sterically tuned peptidomimetic structures. In downstream workflows, its defined (2S,3R) configuration supports reproducible incorporation into synthetic sequences and structure-property studies where side-chain substitution is used to modulate conformation and reactivity.
1. Peptidomimetic Building Block
(2s,3R)-3-Methylglutamic acid is used by medicinal chemistry and chemical biology groups as a glutamate analog building block to construct peptidomimetics and constrained side-chain variants. The methyl substitution at the side-chain carbon provides a practical handle for tuning steric demand around the glutamate motif, which is frequently leveraged in structure-activity relationship (SAR) campaigns and receptor/ligand optimization studies. Researchers typically employ it in custom peptide or peptidomimetic assembly workflows to generate analog libraries where the glutamate geometry and side-chain substitution pattern are controlled for consistent comparison of activity-related properties.
2. Stereodefined Amino Acid Intermediate
(2s,3R)-3-Methylglutamic acid serves as a stereodefined intermediate for downstream synthesis of substituted glutamate derivatives used in specialty chemical manufacturing and pharmaceutical intermediate development. The (2S,3R) configuration enables reproducible preparation of chiral analogs that retain the glutamic acid functional group pattern while introducing a defined methyl-bearing stereocenter for later functionalization. Process and development chemists value this form when they need a reliable starting material for generating further protected amino acid derivatives, side-chain-modified analogs, or reference materials that must match a specific stereochemical identity.
3. Analytical Reference Compound
(2s,3R)-3-Methylglutamic acid is also used as an analytical reference in method development and characterization workflows that involve substituted amino acids, including chiral analysis and impurity profiling. Laboratories preparing LC methods for amino acid derivatives or performing stereochemical verification often rely on authentic standards to confirm retention behavior and to support identification of substituted glutamate components in complex samples. Because the compound is stereochemically specified, it is particularly useful when analysts need to distinguish closely related glutamate analogs that differ by substitution pattern or stereochemistry rather than by gross functional group type.
4. Polymer And Material Functionalization
(2s,3R)-3-Methylglutamic acid is applied in biomaterials and materials chemistry contexts where glutamate-like side chains are incorporated to introduce defined carboxylate functionality for subsequent coupling or surface chemistry. The presence of both amino and carboxyl groups enables its use as a functional monomer or as a precursor for tethered acidic motifs in polymer architectures designed for controlled charge density and interaction with biomolecules. Material developers commonly use stereodefined amino acid derivatives like this to improve reproducibility of functional group placement and to support consistent performance in downstream conjugation, coating, or crosslinking strategies.
