Quality Control

Our Benzoic Acid, 3,4-Dihydroxy-, Phenylmethyl Ester is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and impurity profiles. Certificates of Analysis (COA) documenting results from HPLC, IR, and other relevant methods are available upon request to support your quality assurance protocols.

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). Due to its nature as an easily oxidized compound, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation of quality, especially after opening the original container. Keep away from incompatible materials.
