Quality Control

Our 4-(3-Ethyl-5-Methylcyclohexylidene)-2-Buten-1-Yl Acetate is produced and tested under a strict quality management system. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure identity, purity, and consistency meet the high standards required for fragrance and industrial applications. Certificates of Analysis (COA) detailing specific batch results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at controlled room temperature (15-25°C). Due to its properties of being easily oxidized and highly volatile, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize headspace in opened containers. Keep away from strong acids and oxidizing agents.
