Quality Control

Our Potassium Antimonyl Tartrate Sesquihydrate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. The product is tested against rigorous in-house specifications, which typically include parameters for assay, heavy metal content, and loss on drying. Certificates of Analysis (COA) detailing the results of these quality tests are available for every batch and provided upon request to support your quality assurance processes.

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, which can affect product quality and stability.
