Quality Control

Our trans-5-Methyl-2-(1-Methylvinyl)Cyclohexan-1-One is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatographic purity assessment and identity confirmation, to ensure it meets exacting standards for fragrance and synthetic applications. A Certificate of Analysis (COA) detailing specific results for purity, enantiomeric excess (where applicable), and key physical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at 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 headspace after partial use. Keep away from heat, sparks, and open flame.
