Quality Control

Our Bis(Tetabutylammonium) Hexasulfide is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including assay by titration and identification by FT-IR, to ensure high purity and consistent performance. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) and easily oxidized nature, this material should be stored under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at 15-25°C. Minimize exposure to air and moisture during handling to maintain product integrity.
