Quality Control

Our Chromium (II) Chloride Tetrahydrate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high chemical purity. Each lot is analyzed to confirm identity, assay, and impurity profiles. Certificates of Analysis (COA) documenting these results 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, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture. As the compound is easily oxidized, storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for long-term stability and to maintain product integrity.
