Quality Control

Our Calcium Phosphate Tribasic is manufactured under a rigorous quality management system. Production batches are tested to ensure compliance with relevant pharmacopeial standards such as USP, EP, and FCC for identity, purity, and performance. A comprehensive Certificate of Analysis (COA) documenting all critical parameters is provided with each shipment to guarantee traceability and consistency for your B2B applications.

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); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect flow properties and stability.
