Quality Control

Our 4-Hexen-2-One, 5-Methyl- is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing including GC, HPLC, and NMR to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all specified parameters. Our quality commitment supports applications requiring high-purity intermediates for research and regulated production environments.

Storage

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