Quality Control

Every batch of 2,2-Bis(4-Hydroxyphenyl)Adamantane is manufactured and tested under a strict quality management system. We ensure compliance with relevant industry standards through rigorous analytical controls, including HPLC, GC, and NMR. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each 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, and well-ventilated area at room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents.
