Quality Control

Our Dimethyldiphenylthiuram Disulfide is manufactured under a stringent quality management system. Every batch undergoes comprehensive analytical testing to ensure consistent purity, performance, and compliance with customer specifications. A detailed Certificate of Analysis (COA) documenting key parameters such as assay, melting point, and ash content is provided with each shipment and is available upon request.

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). This material is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed to minimize exposure to atmospheric humidity. Keep away from strong oxidizing agents and heat sources.
