Quality Control

Our Disodium 1-Amino-4-[4-[(Chloroacetyl)Amino]-3-Sulphonatoanilino]-9,10-Dihydro-9,10-Dioxoanthracene-2-Sulphonate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for dye intermediate applications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and consistency.

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, which can affect product quality.
