Quality Control

Our Ethonium is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including identification, assay, and impurity profiling, to ensure it meets the required specifications for your application. Certificates of Analysis (COA) documenting purity, physical characteristics, and test results are available upon request to support your quality assurance and regulatory compliance needs.

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 (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product quality and stability.
