Quality Control

Our 2-Cyclopropene-1-Carbonylchloride,2-Methyl-3-Phenyl-,(R)-(9Ci) is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including chiral purity analysis by HPLC, to confirm identity and specification compliance. Certificates of Analysis (COA) detailing purity, enantiomeric excess, and impurity profiles are available upon request to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic and moisture-sensitive nature, the container should be kept under an inert atmosphere (e.g., nitrogen or argon) after opening. Recommended storage temperature is 2-8°C for long-term stability. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, alcohols, and amines.
