Quality Control

Our Bis(Nonylphenyl) Phenyl Phosphate is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot is analyzed against rigorous internal specifications, which typically include assay, color, acidity, and moisture content. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee compliance with your technical requirements.

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. For long-term storage, consider under an inert atmosphere to maintain optimal quality.
