Quality Control

Every batch of 5-Bromobenzothiazole-2-Sulfonic Acid is manufactured and tested under a strict quality management system. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, detailing key parameters such as purity, identity, and impurity profiles to support your R&D and scale-up activities.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong bases and oxidizing agents.
