Quality Control

Our Benzoic Acid, 3,4-Dihydroxy-, 1-Methylethyl Ester is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and composition. Certificates of Analysis (COA) are provided with every shipment, detailing the results of tests such as HPLC assay, identification by IR spectroscopy, and impurity profiling. We are committed to consistent quality and supply reliability for our global B2B partners.

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). 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 heat and incompatible materials.
