Quality Control

Our Diiodosulfophenylisothiocyanate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity for research and development applications. Each lot is analyzed using advanced techniques including HPLC, NMR, and elemental analysis. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory documentation needs.

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 each use to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong bases, amines, and oxidizing agents.
