Quality Control

Our Entamizole is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets stringent specifications for identity, purity, and impurity profiles. We provide full traceability and support regulatory submissions. Certificates of Analysis (COA) are available for every shipment, detailing results from tests such as HPLC, IR, and residual solvent analysis.

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 to prevent moisture absorption, which can affect product stability and performance.
