Quality Control

Our (2E,4E)-2,4-Nonadiene is produced and handled under a strict quality management system. Each batch undergoes rigorous analytical testing, including GC and GC-MS, to ensure high chemical purity and isomeric integrity. Certificates of Analysis (COA) with detailed specifications are provided to guarantee traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) in a cool, well-ventilated place. Due to its highly volatile and easily oxidized nature, the container must be kept tightly sealed and away from heat, sparks, and open flames. Recommended storage temperature: 2-8°C for long-term stability.
