Quality Control

Our 3,7-Bis(Diethylamino)Phenothiazin-5-Ium is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing including HPLC for purity, NMR and IR for structural confirmation, and loss on drying analysis. We provide a detailed Certificate of Analysis (COA) with every shipment to ensure traceability and compliance with your specifications and relevant industry standards.

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 nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product stability and performance.
