Quality Control

Every batch of our Pyridinium 3-[5-Chloro-2-[2-[5-Chloro-3-(3-Sulfonatopropyl)Benzothiazolin-2-Ylidenemethyl]-1-Butneyl] -3-Benzothiazolio] Propanesulfonate is manufactured under a strict quality management system and undergoes comprehensive analytical testing to ensure identity, purity, and performance consistency. We provide a detailed Certificate of Analysis (COA) with each shipment, which includes key parameters such as assay, absorbance profile, and impurity levels. Our production adheres to ISO 9001 standards, ensuring reliable supply for critical industrial applications.

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 to prevent degradation. For long-term storage, consider using desiccants.
