Quality Control

Our (3E,5E)-2-Methyl-1,3,5-Undecatriene is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography (GC, HPLC) and spectroscopic methods (NMR, IR), to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its sensitivity to oxidation and light, prolonged exposure to air or direct light should be avoided. Keep away from heat, sparks, and open flames.
