Quality Control

Every batch of 2,5-Dimethyl-3-(3-Sulphonatopropyl)Benzothiazolium is manufactured and tested under a strict quality management system. We ensure compliance with relevant industry standards and provide comprehensive Certificates of Analysis (COA) for each shipment, detailing purity, identity, and impurity profiles. Our rigorous QC protocols include multiple analytical checkpoints to guarantee batch-to-batch consistency and reliability for your critical processes.

Storage

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