Quality Control

Our Lithium 5-Iodooctafluoro-3-Oxapentanesulfonate is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and ICP-MS, to ensure high chemical purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your R&D and quality assurance requirements.

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 sealed under an inert atmosphere (e.g., argon or nitrogen) when not in use to prevent degradation.
