Quality Control

Our Xylenedisulphonic Acid is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including assay, impurity profiling, and identity confirmation, to ensure it meets precise customer specifications and industry standards. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and a strong acid/organic solvent; ensure containers are kept tightly sealed to prevent moisture absorption and degradation. Keep away from incompatible materials such as strong bases and oxidizing agents.
