Quality Control

Our production of Potassium Bis[2-[(2-Ethylhexyl)Oxy]Ethyl] Phosphate adheres to stringent quality management systems. Each batch undergoes comprehensive analysis to ensure consistency and meets specifications for critical parameters such as active content, pH, and ionic character. Certificates of Analysis (COA) documenting purity, assay, and physical properties 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 / 59-77°F). Due to its hygroscopic nature, keep the container tightly sealed when not in use to prevent moisture absorption. Keep away from strong oxidizing agents.
