Quality Control

Our Dodeca-3,9-Diene is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced chromatographic and spectroscopic techniques (GC, HPLC) to verify identity, potency, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its easily oxidized nature, contact with air should be minimized. Keep away from heat, sparks, open flames, and strong oxidizing agents.
