Quality Control

Our Oxiranecarboxylic Acid, 2-(1-Hydroxyethyl)-, Ethyl Ester, (R*,R*)- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity and assay determination, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) documenting identity, purity, and enantiomeric excess are available upon request to support your quality and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
