Quality Control

Our 4,5,6,7,7-Pentamethyloct-4-En-3-One is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC, GC-MS, and NMR, to ensure high purity and consistent identity. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee reliable performance in your applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at 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.
