Quality Control

Our Terephthalic Acid, Monohydroxyethyl Ester Sodium Salts is manufactured under a stringent quality management system. Each batch is analyzed to ensure it meets precise specifications for purity, identity, and physical properties. A comprehensive Certificate of Analysis (COA) documenting results for assay, impurity profile, and other critical parameters is provided with every shipment to guarantee consistency and support your quality assurance protocols.

Storage

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