Quality Control

Every batch of Cyclopentanol, 4-Ethyl-2-[3-(Trimethylsilyl)Propyl]-, (1R,2S,4R)-Rel- (9Ci) is manufactured and analyzed under strict quality management protocols to ensure exceptional purity and stereochemical integrity. Our products undergo rigorous quality testing, including chiral HPLC and NMR spectroscopy, to ensure compliance with customer specifications and industry standards. A comprehensive Certificate of Analysis (COA) detailing identity, purity, enantiomeric excess, and impurity profile is provided with each shipment and is available upon request.

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. Keep away from heat, sparks, and open flame.
