Quality Control

Every batch of 1,4,6-Naphthalenetrisulfonic Acid is manufactured and tested under a strict quality management system. We ensure compliance with relevant industry standards and provide comprehensive batch-specific documentation. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is available for all shipments to guarantee traceability and product consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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. Keep away from strong bases and incompatible materials.
