Quality Control

Our 4-Hydroxy-4'-Methoxy-Biphenyl-3-Carboxylic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting specifications for research and industrial use. Certificates of Analysis (COA) documenting purity, assay, and impurity profiles 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, well-ventilated area at room temperature (15-25°C). Due to its light-sensitive nature and potential for oxidation, prolonged exposure to light and air should be minimized. For long-term storage, consider an inert atmosphere.
