Quality Control

Our Ethanone, 1-[(1R,2R)-2-Hydroxy-2-Methylcyclopentyl]-, Rel- (9Ci) is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including chiral purity analysis by HPLC, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) detailing identity, purity, and chiral excess are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
