Quality Control

Our 2,6-Dimethyl-Benzenesulfonicacid is produced under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements for use as a chemical intermediate. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment and is available upon request.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture. Keep away from strong bases and oxidizing agents.
