Quality Control

Our Sodium 4-Hydroxy-3,5-Dimethylbenzenesulphonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including identification, assay, and impurity profiling, to ensure it meets the highest standards of purity and consistency. A comprehensive Certificate of Analysis (COA) documenting all test results is provided with every shipment to guarantee full traceability and compliance with your specifications.

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. Keep away from incompatible materials.
