Quality Control

Our 4 4'-Diisothiocyanato-2 2'-Stilbenedisulfonic Acid is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity verification and spectroscopic methods for structural confirmation, to ensure it meets the high standards required for research and industrial applications. A detailed Certificate of Analysis (COA) is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under anhydrous conditions to prevent degradation. For long-term storage, consider storing under an inert atmosphere.
