Quality Control

Every batch of 2-Sulphofumaric Acid is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the product meets your specific requirements. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is supplied with each shipment, confirming compliance with agreed specifications.

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 opening to prevent absorption of atmospheric moisture. Keep away from incompatible materials such as strong bases and oxidizing agents.
