Quality Control

Every batch of our Sodium 4-[(4-Amino-9,10-Dihydro-3-Methyl-9,10-Dioxo-1-Anthryl)Amino]Toluene-2-Sulphonate is produced under a strict quality management system. We employ advanced analytical techniques including HPLC, NMR, and mass spectrometry to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and physical characteristics is provided with each shipment to guarantee it meets your specific application requirements.

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 sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents.
