Quality Control

Our Tetrachlorogold(1-) is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets the high-purity standards required for sensitive applications in electronics and catalysis. Certificates of Analysis (COA) detailing assay, impurity profiles, and physical specifications are available upon request to support your quality assurance protocols.

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 to prevent absorption of atmospheric moisture, which can affect product stability and performance.
