Quality Control

Our 5-Chloro-2-(2-Methoxyethoxy)-Benzene Sulfonic Acid Sodium is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and tests for residual solvents and heavy metals, to ensure it meets the high standards required for research and industrial synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability, consistency, and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Keep away from heat sources and incompatible materials.
