Quality Control

Our 2,3-Dichloro-6-Hydroxybenzenesulphonic Acid is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and impurity profiles. Certificates of Analysis (COA) documenting these results 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, and well-ventilated area at 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 bases and incompatible materials.
