Quality Control

Our Ralfinamide Mesylate is manufactured under strict quality systems suitable for pharmaceutical applications. It undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing specifications such as assay, related substances, residual solvents, and identification is provided with each batch to support your regulatory and R&D requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccants or inert atmosphere.
