Quality Control

Our Disodium 3,3'-Carbonylbis(4-Hydroxy-6-Methoxybenzenesulfonate) is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and composition. Certificates of Analysis (COA) documenting these results are provided with each shipment to guarantee traceability and batch-to-batch consistency for our customers.

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