Quality Control

Our 7-Methyl-1,4-Dioxacycloheptadecane-5,17-Dione is produced under a strict quality management system. Every batch undergoes rigorous analytical testing, including chromatography and spectrometry, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specific batch results are available upon request. We adhere to industry best practices to meet the stringent requirements of fragrance and synthesis applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, the container should be opaque or stored in dark conditions.
