Quality Control

Our 2,5,5-Trimethyl-3-(1-methylethylidene)-1-cyclohexanone is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including GC, HPLC, 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 at a controlled 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) for long-term preservation and to minimize degradation. Keep away from heat, sparks, and open flame.
