Quality Control

Every batch of Oxiranecarbonyl Chloride, 3-Phenyl-, (2R,3S)- (9Ci) is produced and tested under strict quality management systems. Our products undergo rigorous quality testing, including chiral purity analysis by HPLC, to ensure compliance with exacting R&D and process chemistry standards. Comprehensive Certificates of Analysis (COA) detailing identity, purity, and enantiomeric excess are provided with each shipment.

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). Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from strong acids and incompatible organic solvents.
