Quality Control

Our Trinonylphosphate is manufactured under a strict quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay, color, acidity, and moisture content, to meet precise customer specifications. A Certificate of Analysis (COA) documenting all test results is provided with every shipment to guarantee compliance with your quality 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 acids and strong oxidizers. 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.
