Quality Control

Every batch of 3,4-Phenanthrenediol is manufactured under a strict quality management system. Our products undergo rigorous analytical testing, including HPLC, GC-MS, and NMR, to ensure identity, purity, and consistency meet the high standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment and is available upon request.

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 sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
