Quality Control

Every batch of Oxiranecarboxylic Acid, 3-(Aminocarbonyl)-, Methyl Ester, (2S-Trans)- (9Ci) is manufactured under strict quality management systems. We employ advanced analytical techniques, including chiral HPLC and NMR, to ensure exceptional stereochemical purity and chemical identity. Certificates of Analysis (COA) detailing purity, enantiomeric excess, and impurity profiles are provided with each shipment to support your regulatory and R&D requirements.

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 nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Keep away from incompatible materials such as strong acids, bases, and oxidizing agents.
