Quality Control

Our Diisobutylketone is manufactured under a stringent quality management system. Every batch undergoes comprehensive analytical testing, including gas chromatography (GC), to ensure it meets precise specifications for purity, identity, and physical properties. Certificates of Analysis (COA) documenting these 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 away from heat sources and open flames. Due to its highly volatile nature, keep containers tightly sealed when not in use to prevent evaporation and maintain purity. Recommended storage temperature is 15-25°C.
