Quality Control

Our 5-Hexen-2-One, 3-Methylene- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatography (GC/HPLC) and spectroscopic methods (IR, NMR), to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to light and propensity for oxidation, it is recommended to store this material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flame.
