Quality Control

Our 2-Ethyl-2-heptenal is produced under stringent quality management protocols. Each batch is analyzed to ensure it meets precise specifications for identity, purity, and olfactory profile. Certificates of Analysis (COA) documenting purity (typically by GC), specific gravity, refractive index, and organoleptic properties are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at controlled room temperature (15-25°C). This product is easily oxidized and highly volatile; it is recommended to store under an inert atmosphere (e.g., nitrogen) and keep containers tightly sealed when not in use to prevent evaporation and degradation.
