Quality Control

Our Magnesium 2-Hydroxypropanoate Trihydrate is manufactured under a strict quality management system. Each batch is tested to ensure it meets stringent specifications for identity, purity, and heavy metal content, aligning with relevant pharmacopeial standards (such as USP/NF or Ph. Eur.) and food-grade requirements (FCC). A comprehensive Certificate of Analysis (COA) documenting all test results is provided with every shipment to guarantee traceability and compliance.

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 nature, the container must be kept tightly sealed after opening to prevent moisture absorption and caking.
