Quality Control

Our Tetrakis(Hydroxymethyl)Phosphoniumacetate/Phosphate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and performance for its target applications. Certificates of Analysis (COA) documenting key parameters such as active content, pH, and solubility 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, well-ventilated area at room temperature (15-25°C). Keep away from strong bases and incompatible materials such as strong oxidizing agents. Due to its hygroscopic nature, minimize exposure to atmospheric moisture during handling.
