Quality Control

Our Disodium 1-Amino-9,10-Dihydro-4-[(4-Methyl-2-Sulphonatophenyl)Amino]-9,10-Dioxoanthracene-2-Sulphonate is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting specifications for use as a dye intermediate. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and physical characteristics is provided with each shipment to guarantee traceability and compliance.

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 tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
