Quality Control

Every batch of Oxiranecarbonyl Chloride, 3-Phenyl-, (2R,3S)-Rel- (9Ci) is produced and tested under strict quality management protocols to ensure high chiral purity and chemical integrity, suitable for demanding synthetic applications. Our quality assurance includes comprehensive analytical characterization. Certificates of Analysis (COA) detailing purity, enantiomeric excess, and impurity profiles 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). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from strong acids and incompatible organic solvents.
