Quality Control

Our production of 8-(((4'-Sulfo(1,1'-Biphenyl)-4-Yl)Sulfonyl)Amino)-1,3,6-Naphthalenetrisulfonic Acid adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure consistent performance and specification compliance. Certificates of Analysis (COA) detailing batch-specific results are provided to guarantee supply chain transparency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture. Keep away from strong acids and incompatible organic solvents.
