Quality Control

Our Di(3-Methylhexyl)Phthalate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and reliability. Each lot is tested against rigorous internal specifications, which typically include purity, color, acidity, and specific gravity. A comprehensive Certificate of Analysis (COA) detailing these results is provided with every 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 away from incompatible materials such as strong acids and oxidizing agents. Recommended storage temperature is 15-25°C. Keep container tightly sealed when not in use to minimize moisture absorption and prevent contamination.
