Quality Control

Our production of Bis[17-(Nonylphenoxy)-3,6,9,12,15-Pentaoxaheptadecan-1-Yl] Hydrogen Phosphate adheres to a strict quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is analyzed against stringent in-house specifications, which typically include assay, acid value, pH, and moisture content. A Certificate of Analysis (COA) documenting these results is provided with every shipment 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 each use to minimize moisture absorption, which can affect product performance. Keep away from strong oxidizing agents.
