Quality Control

Our Ethionic Acid is produced and handled under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including assay by titration, identification by FT-IR, and impurity profiling, to ensure it meets exacting standards for purity and consistency. Certificates of Analysis (COA) with detailed batch-specific results are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature and strong acid properties, the container must be kept in a cool, dry, and well-ventilated place. Recommended storage temperature is between 15°C and 25°C. Keep away from incompatible materials such as strong bases and oxidizing agents.
