Quality Control

Our 4,4'-Bi-m-Toluidine Dihydrogen Bis(Sulphate) is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure high purity and consistent performance. Standard quality parameters include assay, identification, and control of key impurities. A comprehensive Certificate of Analysis (COA) documenting all test results 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 (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents.
