Quality Control

Our Exo-Dicyclopentadiene is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC and HPLC analysis, to ensure high purity and consistent isomeric composition. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are provided with every shipment to guarantee compliance with your specific application requirements.

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, keep containers tightly sealed when not in use. Recommended storage temperature is 2-8°C (refrigerated) for long-term stability to minimize polymerization or isomerization.
