Quality Control

Our 2-[[5-(Methoxycarbonyl)-3-(4-Sulphonatobutyl)-3H-Benzothiazol-2-Ylidene]Methyl]-1-Methylquinolinium is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets the high standards required for sensitive applications in dye synthesis and life sciences. Certificates of Analysis (COA) detailing all specifications are available upon request.

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.
