Description

Oxiranecarboxylic Acid, 3-Phenyl-, Ethyl Ester, trans- is a high-purity chiral epoxide building block of significant interest in advanced organic synthesis. Its rigid structure and reactive oxirane ring make it a valuable precursor for creating complex, stereodefined molecules. This compound is essential for researchers and manufacturers in the pharmaceutical and fine chemical industries, particularly for developing active pharmaceutical ingredients (APIs) and specialty agrochemicals where precise stereochemistry is critical.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of enantiomerically pure drugs, including potential cardiovascular and central nervous system (CNS) agents.
• Agrochemical Synthesis: Used in the production of advanced, stereoselective pesticides and herbicides.
• Liquid Crystal & Advanced Material Precursor: Serves as a building block for chiral dopants and other functional materials requiring specific optical properties.
• Asymmetric Catalysis Research: Employed as a standard substrate or ligand precursor in the development and testing of new chiral catalysts.
• Fine Chemical Manufacturing: Utilized in custom synthesis for flavors, fragrances, and other high-value specialty chemicals.

Quality Control

Our Oxiranecarboxylic Acid, 3-Phenyl-, Ethyl Ester, trans- is produced under strict quality management systems. Each batch is characterized and tested to ensure identity, purity, and enantiomeric excess meet the high standards required for research and commercial synthesis. A comprehensive Certificate of Analysis (COA) detailing specifications such as assay (by HPLC or GC), enantiomeric purity, and impurity profile is provided with every shipment.

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, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in amber glass or opaque packaging during storage.
