Quality Control

Our Tetramethylammonium Phthalate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, impurity profile, and moisture content. We adhere to cGMP principles where applicable to support our customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
