Quality Control

Our Bis(8-Methylnonyl) Phthalate is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot is analyzed against stringent internal specifications, which typically include identity confirmation, assay, color, acidity, and moisture content. A Certificate of Analysis (COA) documenting these results is available for 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 strong alkalis and incompatible organic solvents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep containers tightly sealed when not in use to prevent contamination and minimize moisture uptake.
