Quality Control

Our production of Sodium 1-(2-Methylpropyl) 3-[(4-Amino-9,10-Dihydro-9,10-Dioxo-3-Sulphonato-1-Anthracenyl)Amino]Benzoate adheres to stringent quality control protocols to ensure batch-to-batch consistency and purity for industrial synthesis. Each lot is analyzed using advanced techniques like HPLC and spectrophotometry to verify critical parameters such as assay, impurity profile, and color value. Certificates of Analysis (COA) documenting all test results are provided to guarantee the material meets your specific application requirements and internal specifications.

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