Quality Control

Our Tridecyl Acid Phosphate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, acidity, and performance characteristics. We provide full traceability and comprehensive Certificates of Analysis (COA) upon request, supporting compliance with relevant industry standards for intermediates and additives.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as strong bases and oxidizing agents. Due to its acidic nature and sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation of quality. Recommended storage temperature: 15-25°C.
