Quality Control

Our Cyclooct-5-Ene-1,2-Diol is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatography (HPLC, GC) and spectroscopic methods (NMR, IR), to ensure high chemical purity and structural integrity. Certificates of Analysis (COA) detailing purity, enantiomeric excess (where applicable), and impurity profiles are provided with every shipment to guarantee traceability and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
