Quality Control

Our production of Spiro[4.4]Nonane-1,6-Diol, 1-(2-Propenyl)-, (1R,5R,6R)-Rel- (9Ci) adheres to stringent quality protocols to ensure batch-to-batch consistency and high chemical purity. All materials are characterized using advanced analytical techniques including NMR, HPLC, and chiral analysis. A comprehensive Certificate of Analysis (COA) detailing identity, purity, enantiomeric excess, and impurity profiles is provided with each shipment to support your R&D and 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 (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
