Quality Control

Our Magnesium Orthophosphate(V) is produced under a strict quality management system. Each batch is tested to ensure it meets stringent specifications for identity, purity, and heavy metal content. We can supply material compliant with relevant standards such as FCC (Food Chemicals Codex) and USP-NF (United States Pharmacopeia) for applicable grades. A comprehensive Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and consistency.

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); keep the container tightly sealed to prevent caking or degradation due to atmospheric moisture. Separate from strong acids.
