Quality Control

Our Diethyl Beta,Beta'-Dihydroxybenzene-1,4-Dipropionate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC, GC, and IR spectroscopy, to ensure it meets precise purity and consistency standards. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with each shipment to guarantee traceability and compliance.

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. Keep away from strong oxidizing agents and incompatible materials.
