Quality Control

Our Sodium o-[Bis(3,5-Dibromo-4-Hydroxy-o-Tolyl)Hydroxymethyl]Benzenesulphonate is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay, impurity profile, and residual solvent analysis, to ensure it meets precise customer specifications and industry benchmarks. Certificates of Analysis (COA) documenting purity, physical properties, and conformance are available upon request.

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 nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product quality and handling properties.
