Quality Control

Our 1,2,3-Trimethylcyclopentadiene is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support custom purity requirements and can provide material tailored to specific research or production needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and ignition points. Due to its highly volatile nature, containers must be kept tightly sealed when not in use to prevent evaporation and potential concentration changes. Recommended storage temperature is 2-8°C (refrigerated) for extended stability.
