Quality Control

Our 1,4-Naphthalenedicarboxylic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets stringent specifications for purity and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay, identity, and impurity profiles 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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality and handling properties.
