Quality Control

Our 3-(2-Carboxy-Ethanesulfinyl)-Propionic Acid is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including purity assay and identity confirmation, to ensure it meets the high standards required for research and synthesis applications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, appearance, and specific impurities.

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 tightly sealed after each use to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong bases and oxidizing agents.
