Quality Control

Our production of 2,5,8,11-Tetraoxatetradec-13-Ene adheres to stringent quality management protocols. Every batch is analyzed using advanced techniques like GC and NMR to ensure high purity and consistent composition. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. For long-term storage, consider under an inert atmosphere such as nitrogen to minimize potential oxidation of the terminal alkene.
