Quality Control

Our 3,5-Heptadien-2-One, (E,Z)- is produced under strict quality management protocols. Every batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopy (NMR, IR), to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided and 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, dry, well-ventilated area at controlled room temperature (15-25°C). This material is light-sensitive and easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen or argon) to preserve stability.
