Quality Control

Our Pentacyanoferrate (II) is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analysis to ensure identity, purity, and consistency. We provide full traceability and Certificates of Analysis (COA) are available for all shipments, detailing key parameters such as assay, impurity profile, and moisture content.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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 degradation from atmospheric moisture.
