Quality Control

Our 1,5-Dimethylcyclopentene is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the exacting standards required for synthetic applications. Comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place, away from heat, sparks, and open flames. Recommended storage temperature is 2-8°C (refrigerated) for extended stability. Keep container tightly sealed when not in use to prevent evaporation and potential concentration of peroxides over time.
