Quality Control

Our 1-Isopropyl-4,5-Dimethylcyclopentene is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistent performance. A detailed Certificate of Analysis (COA) documenting identity, purity, and impurity profiles is provided with each shipment to support your quality and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat and ignition sources. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep container tightly sealed when not in use to prevent evaporation and degradation.
