Quality Control

Our (3E)-Penta-1,3-Diene is produced and handled under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including GC and HPLC analysis, to verify identity, purity, and the absence of critical impurities. We provide full traceability and Certificates of Analysis (COA) are available upon request to ensure compliance with your specific project requirements.

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. Keep under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation and polymerization. Keep away from strong oxidizing agents.
