Quality Control

Our production of 2-Cyclopenten-1-One, 4,5-Dihydroxy-4-[(1R)-1-Hydroxyethyl]-, (4R,5R)-Rel- (9Ci) adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is characterized using advanced analytical techniques including HPLC, NMR, and chiral analysis to confirm identity, purity, and stereochemical integrity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
