Quality Control

Our 5,6-Dimethylhept-5-En-2-One is produced and handled under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing specific test results, including assay by GC, is provided with every shipment to guarantee it meets your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place away from heat, sparks, and open flame. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize degradation. Keep container tightly sealed when not in use.
