Quality Control

Our Tetrathionic Acid is produced and handled under strict quality protocols to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay and purity verification, to meet exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee product integrity and support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its nature as a strong acid/organic solvent and being easily oxidized, it is recommended to store under an inert atmosphere for long-term stability and minimize exposure to air and moisture.
