Quality Control

Our 1-Cyclopentene-1-Methanol, α-(Dichloromethylene)-2-Hydroxy- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatographic purity assessment and structural confirmation, to ensure it meets the exacting standards required for research and process chemistry. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and consistency for your critical applications.

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). The compound may be sensitive to moisture and prolonged exposure to air; therefore, it is recommended to handle under an inert atmosphere for long-term storage and to allow the container to reach ambient temperature before opening.
