Quality Control

Our Di-n-Octyl Phthalate is manufactured under a stringent quality management system. Each batch is tested against rigorous internal specifications to ensure high purity, consistent performance, and reliable supply. Key parameters such as assay, color, acidity, and specific gravity are verified. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee traceability and compliance with your requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep containers tightly sealed when not in use to minimize moisture absorption and contamination.
