Quality Control

Our 1,4,5,8-Naphthalenetetracarboxylic Acid Tetrapotassium Salt is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and consistency. A Certificate of Analysis (COA) detailing key parameters such as assay, impurity profile, and moisture content is provided with each shipment to guarantee traceability and compliance with your project requirements.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
