Quality Control

Our 1,2-Benzenedimethanesulfonic Acid Disodium Salt is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise chemical and physical specifications. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and compliance for your critical 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 nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product quality and handling properties.
