Quality Control

Our 3-(5-Carboxy-2-Hydroxy-3-Methoxy-Phenyl)-4-Hydroxy-5-Methoxy-Benzoic Acid is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept in a cool, dry place with minimal humidity fluctuation. Recommended storage temperature is 2-8°C for long-term stability. Allow the sealed container to reach room temperature before opening to prevent condensation and moisture ingress.
