Quality Control

Our production of Magnesium 3-Nitronaphthalene-1,5-Disulphonate adheres to stringent quality control protocols to ensure batch-to-batch consistency and purity suitable for industrial synthesis. Each lot is analyzed using advanced techniques like HPLC and titration to verify critical parameters. Certificates of Analysis (COA) documenting identity, assay, and impurity profiles are available upon request to support your quality assurance processes.

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 each use to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
