Quality Control

Our Disodium 2-Heptadecyl-1-[(Sulphonatophenyl)Methyl]-1H-Benzimidazolesulphonate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters are provided to guarantee compliance with your technical requirements and support your own quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect product performance and handling.
