Quality Control

Our 5-Chloro-2-(3-Sulfopropylthio)-3-(3-Sulfopropyl)-Benzothiazolium Inner Salt is produced under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency meet the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing specifications such as assay (HPLC), impurity profile, and physical characteristics are provided and available upon request to support your quality assurance protocols.

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 sealed under anhydrous conditions to prevent degradation. Keep away from incompatible materials.
