Quality Control

Our Heptyl,Undecylphthalate is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. The product is tested against rigorous internal specifications for critical parameters including assay, color, acidity, and moisture content. Certificates of Analysis (COA) documenting full test results are available for every batch to support your quality assurance and regulatory compliance needs.

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 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.
