Quality Control

Our Magnesium Oxide is produced under stringent quality management systems to ensure batch-to-batch consistency and reliability. We offer various grades, including industrial, food (FCC), and pharmaceutical (USP/EP) specifications, with quality verified against relevant pharmacopeial or industry standards. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee compliance with your specific requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent moisture absorption and caking. Store away from incompatible materials such as strong acids.
