Quality Control

Our Potassium Hydrogen -5-Aminobenzene-1,3-Disulphonate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, which includes results from HPLC, IR spectroscopy, and titration methods. Our quality commitment ensures the material meets the stringent requirements for use as a pharmaceutical intermediate and in other high-precision applications.

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 sealed when not in use to prevent absorption of atmospheric moisture, which can affect product quality and handling properties. Keep away from incompatible materials.
