Quality Control

Our 1,2,3,4-Pentanetetracarboxylic Acid is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for industrial and research applications. Certificates of Analysis (COA) documenting purity, identity, and impurity profiles are available upon request to 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 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 may affect product quality.
