Quality Control

Our 2,3-Oxiranedicarboxylicacid,Monomethylester,trans-(9Ci) is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chiral purity analysis by HPLC, to confirm identity, strength, and the absence of critical impurities. Certificates of Analysis (COA) detailing all test results are provided and 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 a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect stability and reactivity. Keep away from incompatible materials such as strong acids, bases, and oxidizing agents.
