Quality Control

Every batch of 1,2-Cyclopentanediol, 1-Ethynyl-3-Methylene-, cis- (9Ci) is produced and analyzed under a strict quality management system. We guarantee high chemical purity and lot-to-lot consistency, which is critical for research and process development. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles 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 (moisture-sensitive) nature, the container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and potential degradation. Recommended long-term storage temperature is 2-8°C.
