Quality Control

Our Benzene-1,4-Diammonium Bis(4-Methylbenzenesulphonate) is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets the highest standards of purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee 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 to prevent moisture absorption, which can affect product stability and performance. Keep away from incompatible materials.
