D-Thyronine is a D-configured amino acid derivative of the thyronine family, featuring an aromatic phenyl ring bearing a hydroxyl substituent and a side chain with a terminal carboxylic acid and an amino group. The molecule contains a primary amino functional group and a carboxyl group that can exist as zwitterionic species in solution, while the phenolic hydroxyl on the aromatic ring provides hydrogen-bonding and potential sites for derivatization. D-Thyronine is used in chemical biology and analytical method development where stereochemically defined thyronine analogues are required for peptide-related studies, molecular labeling, or structure-property investigations involving aromatic amino acid frameworks.
CAT No: CP19202
D-Thyronine is a D-configured amino acid featuring a chiral α-carbon bearing a primary amino group and a carboxylic acid, together with a phenolic side chain characteristic of thyronine derivatives. The aromatic ring and phenolic hydroxyl enable hydrogen-bonding interactions and electrophile-directed derivatization, while the carboxyl and amino functionalities support standard amino acid coupling chemistries and salt formation. D-Thyronine's stereochemistry makes it suitable for stereochemically defined studies of amino acid recognition, racemization control, and side-chain functional transformations. As an amino acid-based intermediate, D-Thyronine can be converted into protected amino acid derivatives, activated esters, or side-chain-modified analogs that feed into peptide building block preparation and downstream synthetic routes.
1. Peptide Synthesis
D-Thyronine is applied in peptide synthesis and peptide coupling chemistry as a stereodefined amino acid building block whose α-amino and α-carboxyl groups participate in amide bond formation. The phenolic side chain can be protected during chain assembly to prevent undesired O-acylation or oxidation, enabling orthogonal deprotection strategies that preserve the D-configuration. D-Thyronine-derived protected amino acid derivatives can be incorporated at specific positions to generate peptides with defined aromatic-phenolic motifs for conformational and binding studies. The resulting peptide scaffolds serve as intermediates for peptidomimetic construction and structure-activity relationship studies in amino acid chemistry and peptide science.
2. Chiral Building Block Development
D-Thyronine is used as a chiral amino acid intermediate for stereoselective synthesis planning, where the D-configuration provides a controlled stereochemical handle for downstream transformations. The presence of both a carboxylic acid and a phenolic hydroxyl supports conversion into protected forms such as N-protected amino acid derivatives and O-protected phenols, facilitating selective functional group manipulation. Side-chain derivatization can be designed to introduce electrophiles, linkers, or reporter groups while maintaining the stereochemical integrity of the α-center. D-Thyronine-based intermediates can therefore be employed in chiral synthesis workflows that require defined absolute configuration for analytical reference materials and synthetic organic chemistry.
3. Chemical Biology And Labeling
D-Thyronine is suitable for chemical biology research and biomolecule labeling workflows because the phenolic hydroxyl and amino acid backbone enable conjugation-ready derivative formation. The compound can be transformed into activated carboxyl derivatives or protected intermediates that support amide coupling to carrier proteins, peptides, or affinity tags, while orthogonal protection strategies help manage the phenolic functionality. D-Thyronine's aromatic-phenolic motif can also be leveraged for affinity-based assays and for creating stereochemically defined probes that distinguish D- versus L-related recognition patterns. Labeled or conjugated D-thyronine derivatives can function as biochemical research intermediates for studying molecular recognition, binding epitopes, and stereochemical effects in amino acid-containing systems.
4. Process Chemistry Intermediate
D-Thyronine is applied in process chemistry and fine chemical synthesis as an amino acid-based feedstock that can be converted into standardized protected derivatives and coupling reagents. The functional group set supports manufacturing-oriented route design, including formation of N-protected amino acid derivatives for controlled peptide coupling and conversion of the carboxyl group into activated intermediates for downstream amide formation. Phenolic hydroxyl handling can be addressed through O-protection and subsequent deprotection steps that align with scalable synthetic sequences and minimize side reactions such as oxidation or uncontrolled acylation. D-Thyronine-derived intermediates can thereby serve as reproducible inputs for pharmaceutical intermediate preparation, specialty chemical production, and industrial synthesis of stereodefined aromatic amino acid derivatives.
5. Analytical Research Standards
D-Thyronine is used in analytical research as a stereochemically defined reference material for method development and identity verification of amino acid mixtures and peptide hydrolysates. The combination of an α-amino acid framework and a phenolic side chain enables chromatographic and spectrometric differentiation when paired with derivatization strategies that target the carboxyl and phenolic hydroxyl groups. D-Thyronine can be incorporated into calibration standards, isotope-labeling workflows, or derivatization schemes that support quantitation and stereochemical assignment of related thyronine analogs. D-Thyronine-based analytical standards and derivatized forms can support quality control and characterization in biochemical research intermediate preparation and synthetic peptide analysis.
