Quality Control

Our 2-Methylenesuccinic Acid, Potassium Salt is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and composition. Certificates of Analysis (COA) documenting these results are provided to guarantee traceability and batch-to-batch consistency for our global B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
