Description

Oxiranecarboxylic Acid, 3-(1E)-1-Propenyl-, Ethyl Ester, (2S,3R)- (9Ci) is a high-purity, stereochemically defined epoxide derivative, serving as a critical chiral building block in advanced organic synthesis. Its precise stereochemistry and reactive oxirane ring make it an invaluable intermediate for constructing complex molecules with high enantiomeric purity. This compound is essential for research and development chemists in the pharmaceutical, agrochemical, and specialty chemical industries seeking to introduce specific chiral centers into target molecules.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs), particularly in the development of novel therapeutics.
• Agrochemical Synthesis: Used in the production of advanced pesticides and herbicides where specific stereochemistry is required for biological activity.
• Ligand and Catalyst Development: Serves as a precursor for creating chiral ligands and organocatalysts used in asymmetric synthesis.
• Fine Chemical Production: Employed in the manufacture of specialty chemicals, flavors, and fragrances that require enantiomerically pure components.
• Academic and R&D: A valuable tool for methodological development in organic chemistry and for studying stereoselective reactions.
• Polymer Modification: Can be used to introduce functional epoxide groups into polymer chains for cross-linking or property enhancement.

Quality Control

Every batch of Oxiranecarboxylic Acid, 3-(1E)-1-Propenyl-, Ethyl Ester, (2S,3R)- (9Ci) is produced under strict quality management systems. Our products undergo rigorous analytical testing, including chiral HPLC and NMR, to ensure high enantiomeric excess (ee) and chemical purity suitable for sensitive synthetic applications. Certificates of Analysis (COA) detailing identity, purity, and stereochemical composition are available upon request, supporting compliance with cGMP and ICH guidelines where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, containers must be kept tightly sealed and may require storage under an inert atmosphere for long-term stability. Keep away from heat, sparks, and open flame.
