Quality Control

Our 4-Acetylamino-2-Hydroxyphenylarsonic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including identification, purity assay, and impurity profiling, to ensure it meets exacting standards for research and synthesis. A Certificate of Analysis (COA) detailing specific results for parameters such as assay (by HPLC), residual solvents, and heavy metals (including arsenic speciation) is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed in a dry environment to prevent absorption of water vapor, which can affect stability and handling properties.
