Quality Control

Our production of 1-Amino-9,10-Dihydro-4-[[3-[(4-Methoxybenzoyl)Amino]Phenyl]Amino]-9,10-Dioxo-2-Anthracenesulfonic Acid Sodium Salt adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analysis including identification, assay, and impurity profiling. Certificates of Analysis (COA) documenting purity, heavy metals, residual solvents, and other critical parameters are provided to support your quality assurance and regulatory needs.

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 opening to prevent absorption of atmospheric moisture, which can affect product stability and performance.
