Quality Control

Our (5E)-Hept-5-En-3-Yn-1-Ol is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopy (NMR, IR), to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended storage temperature is 2-8°C to maintain stability. Due to its hygroscopic and easily oxidized nature, the container must be kept sealed and allowed to reach ambient temperature before opening to prevent moisture ingress.
