Quality Control

Our 1,3-Cyclopentadiene, 1,2,3,4,5,5-Hexamethyl- is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Due to its propensity for oxidation, the container should be kept sealed under positive pressure of inert gas when not in use. Recommended long-term storage temperature is 2-8°C.
