Quality Control

Our (11Br)-2,6-Bis(4-Chlorophenyl)-4-Hydroxy-4-Oxide-Dinaphtho[2,1-D:1',2'-F][1,3,2]Dioxaphosphepin is produced under strict quality management protocols. Each batch undergoes comprehensive analytical characterization to ensure identity, purity, and consistency. We provide full traceability and Certificates of Analysis (COA) detailing key parameters such as assay (HPLC), identity confirmation (NMR, IR), and impurity profiles. Our quality commitment aligns with cGMP principles where applicable for advanced intermediate synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants or an inert atmosphere.
