Quality Control

Our Magnesium Dihydrogenpyrophosphate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity and compliance with agreed specifications. Certificates of Analysis (COA) documenting key parameters such as assay, heavy metal content, and loss on drying are provided with every shipment. We can support production to meet various standards, including Food Grade (FCC) or technical specifications, based on customer requirements.

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). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after initial opening to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
