Quality Control

Our Neoarsphenamine is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including identification, purity assay, and impurity profiling, to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat and incompatible materials.
