3-(2-Thiazoyl)-D-alanine is a D-configured amino acid derivative in which the side chain bears a 2-thiazoyl (thiazole/thiocarbonyl-containing heteroaryl) substituent, positioning it as a non-proteinogenic analogue for peptide and chemical-biology studies. The molecule contains a free amino group and a carboxyl group along with the heteroaryl side chain, enabling it to be handled as an amino acid building block while offering a distinct aromatic/heteroaryl functionality for binding, conjugation, or spectroscopic readouts. In synthetic workflows, it is used as a substrate-like amino acid component to construct modified peptides or to introduce the thiazoyl motif into larger biomolecular frameworks for structure-activity studies, labeling strategies, or analytical method development.
CAT No: CP23902
3-(2-Thiazoyl)-D-alanine is a D-configured alanine derivative bearing a thiazole-type heteroaryl substituent at the 3-position, providing a rigid, aromatic side-chain functionality distinct from proteinogenic amino acids. This heteroaryl group makes the compound a useful building block for medicinal chemistry and heteroaromatic scaffold assembly, where stereochemical control at the amino acid center is often required. In research settings, it is typically handled as a specialized amino acid-derived intermediate rather than a direct feedstock for native protein incorporation.
1. Medicinal Chemistry Building Block
3-(2-Thiazoyl)-D-alanine is used in small-molecule and peptidomimetic design workflows to introduce a thiazole-containing motif with defined stereochemistry. Medicinal chemistry groups employ this amino acid derivative to construct analog series where the heteroaryl side chain contributes to binding interactions, conformational preferences, or physicochemical tuning. Its amino acid-derived framework supports downstream conversion into amide, ester, or coupling-ready forms for incorporation into larger structures, including linker-bearing pharmacophore assemblies and heteroaryl-substituted cyclic or acyclic scaffolds.
2. Peptidomimetic And Conjugate Synthesis
3-(2-Thiazoyl)-D-alanine is frequently selected for the synthesis of peptidomimetics and amino-acid-based conjugates where a non-proteinogenic, stereodefined residue is required to modulate structure and chemical identity. Chemical biology and drug discovery teams use it to build constrained or heteroaryl-functionalized fragments that can be further elaborated into larger peptide-like architectures, including side-chain-modified analogs and specialized coupling intermediates. The thiazoyl functionality provides a chemically distinct handle for subsequent derivatization steps, enabling targeted assembly of research reagents and structure-activity relationship (SAR) libraries.
3. Pharmaceutical Intermediate Development
3-(2-Thiazoyl)-D-alanine serves as a practical pharmaceutical intermediate for industrial and development chemistry programs that require a heteroaryl amino acid motif as a controlled input. Process development and custom synthesis teams incorporate this building block into late-stage intermediate routes to prepare thiazole-containing intermediates used for further functional group elaboration. The defined D-stereocenter is particularly valuable when stereochemical purity must be maintained through downstream transformations, supporting consistent material quality for screening compounds and development candidates.
4. Analytical Reference Compound Use
3-(2-Thiazoyl)-D-alanine is also used as a defined-structure reference material in analytical method development and characterization workflows for heteroaryl amino acid derivatives. Analytical chemistry groups rely on such stereochemically defined standards when developing LC-MS or HPLC methods to monitor intermediates, assess impurity profiles, or confirm identity during synthesis and purification. The presence of the thiazoyl aromatic system supports straightforward chromatographic and mass spectrometric detection, making it useful for method validation and routine quality control of related intermediate batches.
