Quality Control

Our 1,11-Dodecadiene is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including GC, GC-MS, and NMR, to verify identity, purity, and the absence of critical impurities. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all relevant specifications. We support compliance with global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; ensure containers are properly sealed after each use to minimize exposure to air. Keep away from heat, sparks, and open flames.
