Quality Control

Our Imidodisulfurylfluoride is produced under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including assay by titration and identification by FT-IR and NMR spectroscopy, to ensure high purity and consistency. Certificates of Analysis (COA) detailing all specifications are provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and reactive nature, store in a cool (2-8°C), dry, and well-ventilated area under an inert atmosphere. Keep away from strong acids, organic solvents, and moisture. Containers must be kept tightly sealed and upright to prevent leakage and pressure build-up.
