Quality Control

Our 1-Nitroanthraquinone-5-Sulfonic Acid Sodium Salt is manufactured under strict quality control protocols to ensure high purity and batch-to-batch consistency. The product undergoes rigorous analytical testing, including HPLC for assay and purity determination. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available for every batch upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture.
