Quality Control

Our Phosphoric Acid, Diphenyl Tetradecyl Ester is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. All materials are subjected to comprehensive analytical testing, including HPLC, GC, and FTIR for identity and assay confirmation. A Certificate of Analysis (COA) detailing purity, physical properties, and impurity profiles is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Keep away from strong bases and incompatible materials such as strong oxidizing agents. The container must be kept tightly closed to prevent moisture absorption.
