Quality Control

Our Sodium Thioantimonate (V)-9-Hydrate is manufactured under strict quality protocols. Each batch undergoes comprehensive analysis to ensure high chemical purity and consistency. We provide detailed Certificates of Analysis (COA) that document key parameters such as assay, heavy metal content, and loss on drying, supporting traceability and compliance for your R&D and production needs.

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 sealed immediately after use to prevent absorption of atmospheric moisture and potential caking or decomposition.
