Quality Control

Our Disodium 2-(2,3-Bis-Sulfanylpropyl-(2-Sulfonatoethyl)Amino)Ethanesulfo Nate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay, impurity profiling, and identity confirmation, to ensure it meets precise customer specifications and consistent high purity. Certificates of Analysis (COA) documenting all critical parameters are available upon request and are provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) and easily oxidized nature, the container must be kept tightly sealed after each use to minimize exposure to atmospheric moisture and oxygen. For long-term storage, consider using an inert gas blanket.
