Description

L-Allothreonine, 2-(2-Aminoethyl)- (9Ci) is a specialized, non-proteinogenic amino acid derivative of significant interest in advanced organic synthesis and pharmaceutical research. Its unique structure, featuring both an aminoethyl side chain and the L-allothreonine backbone, makes it a valuable chiral building block for the development of novel bioactive compounds and complex molecules. This high-purity intermediate is primarily sought by research institutions and chemical manufacturers in the pharmaceutical, agrochemical, and fine chemical sectors for applications in drug discovery, peptide mimetics, and catalyst development.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the research and development of new active pharmaceutical ingredients (APIs), particularly for drugs targeting neurological and metabolic pathways.
• Peptidomimetics & Bioactive Molecule Synthesis: Used to construct peptide analogs and other bioactive molecules where its specific stereochemistry and functional groups are critical for biological activity.
• Agrochemical Research: Employed as a building block in the synthesis of novel herbicides, fungicides, and plant growth regulators with enhanced selectivity.
• Chemical Biology & Proteomics: Utilized in the design and synthesis of chemical probes, enzyme inhibitors, and tools for studying protein function and interactions.
• Catalyst & Ligand Development: Acts as a precursor for chiral ligands and organocatalysts used in asymmetric synthesis to induce stereoselectivity.
• Fine Chemical Synthesis: Incorporated into the production of specialty chemicals, flavors, and fragrances requiring high-purity, optically active intermediates.

Quality Control

Our L-Allothreonine, 2-(2-Aminoethyl)- (9Ci) is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity verification by HPLC, to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent product degradation and clumping.
