Quality Control

Every batch of Aniline-3-β-Ethyl Sulfonyl Sulfate-6-Sulfonic Acid is produced and tested under a strict quality management system. We ensure compliance with relevant industry standards for fine chemical intermediates. Comprehensive testing includes identity confirmation, purity assay, and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to exclude moisture. Keep away from incompatible materials such as strong bases and oxidizing agents.
