3-(2-Thiazoyl)-DL-alanine is a DL-form amino acid derivative in which the alanine backbone bears a thiazoyl substituent at the 3-position, classifying it as an unnatural, structurally modified amino acid for peptide-related chemistry. The molecule contains a free amino group and a carboxyl group on the side of the alanine framework, while the thiazoyl moiety provides an additional heteroaromatic functionality that can participate in coordination, hydrogen-bonding interactions, or chemical conjugation depending on the reaction conditions. It is used as a building block or substrate analogue in synthetic studies and structure-activity investigations where incorporation of a thiazoyl-bearing alanine residue is needed to modulate physicochemical properties or to introduce a functional heteroaromatic handle for downstream derivatization and analytical method development.
CAT No: CP23903
3-(2-Thiazoyl)-DL-alanine is a DL (racemic) amino acid derivative bearing a thiazole-containing heteroaryl side chain, making it a useful building block for heteroaromatic peptide and peptidomimetic design. Its amino acid functionality supports incorporation into synthetic sequences, while the thiazole motif provides a chemically distinctive aromatic handle for medicinal chemistry and structure-activity relationship studies. As a racemate, it is commonly selected when stereochemical purity is not required for downstream screening, method development, or library synthesis.
1. Peptidomimetic Building Blocks
3-(2-Thiazoyl)-DL-alanine is used by medicinal chemistry and peptide chemistry groups to assemble peptidomimetic scaffolds that incorporate a thiazole-containing side chain. Researchers often employ this amino acid derivative to generate analog series where the heteroaryl group is retained while other backbone or substituent features are varied, enabling SAR work focused on aromatic electronics and heterocycle-driven interactions. In custom peptide synthesis workflows, it serves as a heteroaryl-bearing amino acid building block for solution-phase or solid-phase assembly of modified peptides and hybrid constructs.
2. Heteroaryl Peptide Libraries
3-(2-Thiazoyl)-DL-alanine supports peptide library construction where thiazole functionality is used as a structural motif for screening binding motifs, conformational preferences, or protease-recognition trends in non-clinical research settings. Because the material is provided as a DL mixture, it is frequently chosen for parallel synthesis campaigns that prioritize throughput over stereodeconvolution at the early discovery stage. Library developers use the thiazole-containing side chain to diversify aromatic character across analogs, while the amino acid backbone enables consistent coupling into defined peptide sequences produced for downstream characterization.
3. Pharmaceutical Intermediate Development
3-(2-Thiazoyl)-DL-alanine is also applied as a pharmaceutical intermediate building block for the preparation of thiazole-functionalized fragments used in medicinal chemistry programs. Process and R&D chemists rely on amino acid-derived heteroaryl intermediates to access substituted heteroaromatic motifs that can be further transformed into more complex structures, including side-chain-modified analogs and heterocycle-bearing intermediates for lead optimization. The racemic nature is often acceptable for intermediate-stage synthesis where stereochemical resolution can be deferred until later stages of development or when screening does not require enantiopure material.
