Quality Control

Our (E)-Hex-3-Enyl Propionate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC and GC-MS, to ensure high purity, consistent olfactory profile, and compliance with relevant industry standards for flavor and fragrance ingredients. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at 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 flames.
