Quality Control

Our 3-Methyl-3-Hepten-2-One is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including GC, IR, and NMR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters 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 away from heat sources and incompatible materials. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Recommended storage temperature: 2-8°C.
