Quality Control

Our Cumenedisulphonic Acid is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay, impurity profile, and physical characteristics. Quality specifications can be tailored to meet specific customer requirements and industry standards.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture. Keep away from strong bases and incompatible materials.
