Description

Ethyl (S)-3,4-Epoxybutanoate is a high-value chiral epoxide ester, a crucial building block in asymmetric synthesis. Its enantiopure nature makes it indispensable for producing optically active intermediates with high stereochemical fidelity. This compound is primarily sought by research institutions and manufacturers in the pharmaceutical and fine chemical sectors for developing active pharmaceutical ingredients (APIs) and advanced materials.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of β-blockers, antiviral agents, and other bioactive molecules requiring specific stereochemistry.
• Asymmetric Synthesis: Used in stereoselective ring-opening reactions, nucleophilic additions, and other transformations to construct complex molecular architectures.
• Agrochemical Research: Serves as a precursor for developing enantiomerically pure herbicides, fungicides, and plant growth regulators.
• Ligand and Catalyst Development: Employed in the preparation of chiral ligands and organocatalysts for use in homogeneous catalysis.
• Fine Chemical Production: Utilized in the manufacture of specialty chemicals, flavors, and fragrances where optical purity is critical.
• Academic & Industrial R&D: A valuable reagent for methodological studies in organic chemistry and process development.

Quality Control

Our Ethyl (S)-3,4-Epoxybutanoate is produced under stringent quality management systems. Each batch is characterized and tested to ensure high chemical and optical purity, with critical parameters including assay, enantiomeric excess (e.e.), and impurity profile monitored via advanced analytical techniques. A comprehensive Certificate of Analysis (COA) detailing specifications and test results is provided with every shipment to guarantee traceability and compliance with your research or production standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources, open flames, and incompatible materials such as strong acids, bases, and oxidizing agents. Due to its light-sensitive nature, containers should be kept in opaque packaging or amber glass.
