Quality Control

Our 5-Methyloct-3-En-2-One is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC and GC-MS analysis, to ensure identity, purity, and olfactory profile consistency. Certificates of Analysis (COA) detailing specific batch results are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at 15-25°C. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) after opening to maintain optimal quality and shelf life. Keep away from heat, sparks, and open flame.
