Quality Control

Our Sodium (2,3-Dihydroxypropyl) Phthalate is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise specifications. A Certificate of Analysis (COA) documenting purity, physical properties, and conformance is provided with every shipment to guarantee traceability and batch-to-batch consistency for your critical applications.

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 nature, the container must be kept tightly sealed after opening to prevent moisture absorption and caking. Keep away from incompatible materials such as strong oxidizing agents.
