Quality Control

Our Butethamine is manufactured under strict quality management systems. 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, related substances, and residual solvents is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

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