Quality Control

Our Dichloro[2,2'-Dithiobis[Benzothiazole]]Zinc is produced under strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot undergoes rigorous analytical testing, including assay, identification, and impurity profiling. Certificates of Analysis (COA) documenting purity and key physical-chemical parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

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