Quality Control

Our Mercurous Chloride is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analysis, including assay, identification, and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its light-sensitive and easily oxidized nature, it is recommended to store under an inert atmosphere for long-term stability. Keep container tightly sealed when not in use to minimize exposure to air and moisture.
