Quality Control

Our Diiron Trimalate 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. Certificates of Analysis (COA) are provided with every shipment, detailing results for key parameters such as assay, iron content, and moisture. We can support compliance with relevant standards for pharmaceutical (USP/EP) and food-grade (FCC) applications upon request.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product stability and handling properties.
