Quality Control

Our 1,3-Dilinolein is produced and handled under strict quality management protocols. Each batch is analyzed to ensure identity, purity, and consistency, with specifications tailored to meet the requirements of research and industrial applications. A comprehensive Certificate of Analysis (COA) documenting purity (typically by HPLC), identity confirmation, and relevant impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C to minimize oxidation. For long-term storage, keep the material frozen at -20°C or below. Allow the container to reach room temperature before opening to prevent moisture condensation.
