Quality Control

Our 3,3'-Dimethoxy-4,4'-Dihydroxybiphenyl is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting standards for high-purity intermediates. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee traceability and consistency for your critical applications.

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 light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize degradation. Keep away from strong oxidizing agents.
