Quality Control

Our Eicosanedioic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay by titration, identification by FT-IR, and quantification of key impurities by HPLC, to ensure it meets the required specifications for high-purity industrial and chemical synthesis applications. A Certificate of Analysis (COA) documenting purity, physical properties, and test results is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
