Quality Control

Our Gold(III) Chloride Dihydrate is produced and tested under stringent quality management protocols to ensure batch-to-batch consistency and high chemical purity. Each lot is analyzed to meet exacting specifications, with comprehensive testing for gold content, impurity profiles, and solution clarity. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory 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). This material is hygroscopic (moisture-sensitive) and should be handled in a dry environment to prevent clumping or decomposition. Keep away from incompatible materials such as strong acids, organic solvents, and reducing agents.
