Quality Control

Our 1,3,5-Undecatriene is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as identity, assay, and impurity profile. We are committed to meeting the stringent requirements of research and industrial applications, with specifications available to support regulatory and quality documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated place. Due to its highly volatile and easily oxidized nature, prolonged exposure to air, heat, or light should be avoided. Recommended storage temperature is 2-8°C for long-term stability.
