Quality Control

Our Strontium Citrate Dibasic is manufactured under a strict quality management system. Each batch is tested to ensure it meets stringent specifications for identity, purity, and composition. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay, heavy metals, and loss on drying. The product is suitable for applications requiring high-purity ingredients, and we can support compliance with relevant standards such as USP-NF or FCC upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry place at controlled room temperature (15-25°C). Keep the container tightly sealed after each use to prevent absorption of moisture from the air, which can affect product quality and flow characteristics.
