Quality Control

Our Phosphorous Acid Ditridecylphenyl Ester is manufactured under a strict quality management system to ensure batch-to-batch consistency and reliability. The product undergoes rigorous analytical testing, including assay and impurity profile determination, to meet exacting industry specifications. A Certificate of Analysis (COA) detailing purity and key parameters is provided with each shipment 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 controlled room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen) after opening to maintain purity and prevent degradation. Keep away from strong oxidizing agents.
