Quality Control

Our Diisodecyl Phenyl Phosphate is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. The product is tested against rigorous internal specifications that assess key parameters such as assay, acid value, color, and moisture content. A Certificate of Analysis (COA) detailing 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 away from strong acids, bases, and oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to minimize moisture absorption.
