Quality Control

Our Sulfocholine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, NMR for structural confirmation, and tests for residual solvents and heavy metals, to ensure it meets the high standards required for research and industrial applications. Certificates of Analysis (COA) detailing all specifications are 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). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect product quality and stability.
