Quality Control

Every batch of our benzothiazolium dye is produced under strict quality management protocols to ensure consistency and performance. We provide comprehensive Certificates of Analysis (COA) that detail purity, identity, and key optical properties. Our quality systems are designed to support research, development, and industrial scale-up with reliable, traceable materials.

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 low-humidity environment. For long-term storage, consider desiccants or an inert atmosphere to preserve stability.
