Quality Control

Our Tetramethylene Phosphate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and high purity, meeting the specifications required for industrial and research applications. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance.

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 degradation from atmospheric moisture. Keep away from incompatible materials.
