Quality Control

Our 4,4'-Biphenyldiol, 2,2'-Dipropyl- is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high-purity standards required for advanced synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key specifications and test results.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its nature as a compound that is easily oxidized (store under inert atmosphere), it is recommended to handle under an inert atmosphere such as nitrogen for long-term storage or after opening.
