Quality Control

Our production of Sodium 1-Amino-9,10-Dihydro-4-[[3-[[(2-Hydroxyethyl)Amino]Sulphonyl]-4-Methylphenyl]Amino]-9,10-Dioxoanthracene-2-Sulphonate adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity for industrial applications. Each lot undergoes comprehensive analysis including identity confirmation, purity assay, and impurity profiling. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory compliance needs.

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 opening to prevent moisture absorption and potential degradation.
