Quality Control

Our Ellagic Acid is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. The product is tested against rigorous in-house specifications, which may include identity confirmation by FT-IR, purity assay by HPLC, and limits for residual solvents and heavy metals. Certificates of Analysis (COA) documenting all 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). This material is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed to prevent absorption of atmospheric moisture.
