Quality Control

Our 2-Aziridinecarboxylicacid,1-Ethyl-,Ethylester,(-)-(9Ci) is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity determination by HPLC, to ensure high chemical and isomeric purity suitable for advanced synthetic applications. Certificates of Analysis (COA) with detailed chromatographic data are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, the container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation. Recommended long-term storage temperature is 2-8°C.
