Quality Control

Every batch of 2-(n-Decyl)Aminonaphthalene-6-Sulfonic Acid is produced and tested under a strict quality management system. We ensure the product meets high-purity standards suitable for industrial and research applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee consistent quality and traceability.

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. Keep away from strong acids and incompatible materials.
