Quality Control

Our Teflic Acid is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, impurity profiling, and verification of critical physical properties. A Certificate of Analysis (COA) detailing all test results is provided with every shipment. We support compliance with global regulatory frameworks, including REACH, and can supply material suitable for research and commercial applications under cGMP guidelines where required.

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). Due to its highly hygroscopic and strong acid nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption and degradation. Store away from incompatible materials such as strong bases, oxidizing agents, and reactive metals.
