3-(4-Pyridyl)-DL-Alanine is a DL (racemic) alanine derivative bearing a 4-pyridyl substituent on the side chain, classifying it as a nonstandard amino acid useful for peptide and chemical biology applications. The molecule contains a primary amino group and a carboxyl group characteristic of amino acids, while the pyridine ring provides a basic heteroaromatic functionality that can participate in coordination and acid-base behavior during synthesis and analytical characterization. As a defined side-chain-modified building block, it is employed in the preparation of peptide analogues and structure-activity studies where incorporation of a pyridyl aromatic handle supports binding, labeling strategies, or physicochemical property modulation.
CAT No: CP23003
3-(4-Pyridyl)-DL-Alanine is a DL (racemic) alanine derivative bearing a 4-pyridyl substituent on the side chain, providing a basic aromatic nitrogen that can participate in coordination chemistry and serve as a distinctive structural handle in analytical and materials contexts. As an amino acid building block, it is commonly selected when researchers need a polar heteroaromatic motif alongside an amino-acid backbone for incorporation into synthetic intermediates, peptide-like scaffolds, or chelating/ligand frameworks. Its stereochemical mixture is frequently acceptable for method development, library synthesis, and comparative structure-property studies where enantiopurity is not the primary requirement.
1. Ligand And Chelator Building
3-(4-Pyridyl)-DL-Alanine is used as a heteroaromatic amino acid building block to construct ligands and chelating motifs for metal coordination studies in chemical biology and materials research. The pendant 4-pyridyl nitrogen offers a reliable coordination site, while the amino-acid functionality supports downstream derivatization into amide, ester, or backbone-modified ligands that can be screened for binding behavior in solution-phase assays. Researchers often choose this racemic form for exploratory synthesis, library generation, and comparative evaluation of pyridyl-containing coordination scaffolds without requiring enantiopure inputs.
2. Peptide-Like Scaffold Synthesis
3-(4-Pyridyl)-DL-Alanine is frequently incorporated into peptide-like structures and peptidomimetic building blocks to introduce a pyridyl aromatic side chain that can influence conformation, polarity, and intermolecular interactions. In custom peptide synthesis and medicinal chemistry research, this amino acid derivative helps generate analog series where a heteroaromatic group is used to probe structure-activity relationships, binding-site interactions, or physicochemical trends across closely related scaffolds. The DL stereochemistry supports practical synthesis workflows for analog development, especially when the goal is to compare structural effects rather than isolate a single stereochemical pathway.
3. Pharmaceutical Intermediate Development
3-(4-Pyridyl)-DL-Alanine serves as a practical intermediate for preparing heteroaromatic amino acid derivatives and substituted scaffolds used in medicinal chemistry and specialty chemical manufacturing. The combination of an amino-acid backbone with a 4-pyridyl group enables conversion into downstream building blocks that retain a useful heteroaromatic handle for further functionalization, such as attachment to larger molecular frameworks via standard derivatization chemistry. Development teams commonly select this compound when they need a robust, identifiable pyridyl-containing amino acid precursor for stepwise synthesis of more complex intermediates used in lead optimization and analog synthesis.
4. Analytical And Reference Standards
3-(4-Pyridyl)-DL-Alanine is also used in analytical method development and reference preparation where a pyridyl-containing amino acid derivative provides a structurally distinctive analyte for chromatography and mass spectrometry workflows. Laboratories may employ it to support calibration strategies, internal or external standard preparation, and identity confirmation for synthetic mixtures or reaction monitoring when a 4-pyridyl motif is expected in the target product set. The stable, non-volatile heteroaromatic character of the side chain makes it a useful benchmark compound for validating analytical performance during development of amino-acid-derived intermediates.
