Quality Control

Our Diisooctyl Phenyl Phosphate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and compliance with industry specifications. Certificates of Analysis (COA) documenting key parameters such as assay, acidity, color, and specific gravity 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 away from strong acids, oxidizing agents, and heat sources. Due to its nature as an organic phosphate ester, it is recommended to store under an inert atmosphere (e.g., nitrogen) to minimize potential oxidation. Recommended storage temperature is 15-25°C.
