Quality Control

Our Bis-2(Bis(2-Hydroxyethyl)Sulphoniumethyl)Sulphidedichloride is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing including assay, impurity profiling, and identity confirmation to ensure consistent purity and performance. Certificates of Analysis (COA) documenting all relevant specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
