Quality Control

Our Bis(Triethylammonium) Sulphite is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including assay, identification, and impurity profiling, to ensure it meets high-purity standards suitable for industrial and research applications. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and test results is provided with each shipment to guarantee traceability and compliance.

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 and easily oxidized nature, it is recommended to handle under an inert atmosphere (e.g., nitrogen or argon) for long-term storage and to minimize exposure to moisture and air.
