Quality Control

Our 8-Amino-1,3,6-Naphthalenetrisulfonic Acid Sodium Salt is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing specifications such as assay (by HPLC), moisture content, and sulfonate content is provided and 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 sealed to prevent absorption of atmospheric moisture.
