Quality Control

Our S,S'-Methylenebis(N,n-Diisobutyldithiocarbamate) is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise specifications for industrial use. Certificates of Analysis (COA) documenting purity, physical properties, and performance characteristics are available upon request to support your quality assurance protocols.

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 after each use to prevent absorption of atmospheric moisture. For long-term storage, consider using an inert atmosphere to minimize oxidation.
