Quality Control

Our 1-[23-(Isotridecyloxy)-3,6,9,12,15,18,21-Heptaoxatricos-1-Yl] Dihydrogen 2-Sulphonatosuccinate is manufactured under a cGMP-compliant quality management system (ISO 9001). Every production batch undergoes rigorous analytical testing to ensure it meets precise specifications for active content, pH, moisture, and performance characteristics. A comprehensive Certificate of Analysis (COA) documenting identity, purity, and key physical parameters is provided with each shipment and is available upon request.

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/59-77°F). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from strong oxidizing agents.
