Quality Control

Our 9-Diethylamino-5-(4,6-Dichloro-S-Triazinyl)-9H-Benzo[A]Phenoxazine Chloride is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for sensitive synthesis processes. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
