Quality Control

Our (1R)-1-Cyclopropyl-1,2-Ethanediol is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis by HPLC, to ensure compliance with exacting R&D and process chemistry standards. Certificates of Analysis (COA) detailing identity, purity, and enantiomeric excess are provided and available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance.
