Quality Control

Our production of Cyclopenta[C]Pyran-5(1H)-One, 3,4,4A,7A-Tetrahydro-1,4-Dihydroxy-3-(Hydroxymethyl)-7-Methyl-, (1S,3R,4S,4As,7As)- (9Ci) adheres to stringent quality management protocols to ensure batch-to-batch consistency and high chemical purity. Each lot is characterized using advanced analytical techniques including HPLC, GC, NMR, and chiral analysis to confirm identity, purity, and stereochemical integrity. Certificates of Analysis (COA) detailing all relevant specifications are provided and can be tailored to meet specific customer or regulatory requirements.

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. For long-term storage, consider using desiccants or an inert atmosphere.
