Quality Control

Our Fluorosulfuric Acid, 2-Naphthalenyl Ester is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including HPLC, GC, NMR, and FTIR, to ensure high chemical purity and identity. We provide full traceability and Certificates of Analysis (COA) are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents.
