Quality Control

Our (Trimethylsilyl)Cyclopentadiene, Mixture Of Isomers is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistent isomer composition suitable for sensitive synthetic applications. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use and stored away from heat and ignition sources. Keep under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to maintain stability.
