Quality Control

Our Disodium Oxybis[Methylbenzenesulphonate] is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and consistency. Certificates of Analysis (COA) documenting key parameters such as assay, moisture content, and impurity profiles are provided with every shipment to guarantee reliable quality and traceability for your critical processes.

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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
