Quality Control

Our 4-(3-Ethyl-5-Methylcyclohexyl)-2-Butenal is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC and HPLC analysis, to ensure high purity and consistent organoleptic profile. Certificates of Analysis (COA) detailing identity, purity, and impurity levels are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from heat, sparks, and open flames.
