Quality Control

Our Methyl 3-Methylbenzothiazolium Sulphate is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements of our industrial and research clients. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
