Quality Control

Our Cyclopenta-1,3-Diene is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including purity assay and impurity profiling via GC and GC-MS. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place, preferably under an inert atmosphere (e.g., nitrogen) to minimize polymerization and oxidation. Recommended storage temperature is 2-8°C. Keep away from heat, sparks, and open flames.
