Quality Control

Our n-n-Octadecyl-4-Stilbazole Bromide is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (NMR, IR), to ensure it meets the high standards required for research and industrial applications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment.

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 nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can affect product stability and performance.
