Quality Control

Our Endo-Dicyclopentadiene is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing, including chromatography (GC/HPLC) and spectroscopy, to ensure high purity and isomer specificity. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flames. Due to its highly volatile nature, containers must be kept tightly sealed when not in use to prevent evaporation and concentration changes. Recommended storage temperature is 2-8°C (36-46°F) to minimize dimerization or degradation. Keep away from strong oxidizing agents.
