Quality Control

Our 1,2,4-Benzenetricarboxylic Acid is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and physical properties. Certificates of Analysis (COA) are provided with every shipment, detailing key parameters such as assay, moisture content, and impurity profiles. We are committed to supplying material that meets the high standards required for industrial and fine chemical synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality and handling properties. Keep away from incompatible materials such as strong bases and oxidizing agents.
