Quality Control

Our Calcium Phthalate Hydrate is produced under a strict quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including identification, assay, and impurity profiling. Certificates of Analysis (COA) documenting purity and key specifications are available upon request to support your quality assurance protocols.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product quality and flow properties.
