Quality Control

Our 1-Methyl-4-p-Dimethylamino-B-Aza-Styryl-Quinolinium-Iodide is produced under stringent quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets exacting research and development grade standards. Comprehensive Certificates of Analysis (COA) with detailed chromatographic and spectral data are provided to guarantee traceability and batch-to-batch consistency.

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 desiccated environment to prevent degradation. For long-term stability, consider storage under an inert atmosphere.
