Quality Control

Our Sodium Sulfosalicylate Dihydrate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and impurity profiles. Certificates of Analysis (COA) documenting these results are provided and can be tailored to meet specific customer or regulatory requirements, including those for pharmaceutical and analytical reagent grades.

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 nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect product stability and performance.
