Quality Control

Our 1-Amino-4-(1-Naphthyl)Aminoanthraquinone-2-Sulfonicacidsodiumsalt is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting specifications for use in sensitive synthesis processes. Certificates of Analysis (COA) documenting key parameters such as assay, impurity profile, and heavy metal content are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
