TETRAPOTASSIUM HEXACYANOFERRATE, CAS#13943-58-3, commonly referred to as yellow prussiate of potash. The commercial trihydrate form is K₄Fe(CN)₆·3H₂O, which appears as yellow crystalline particles with saline taste.
This chemical compound dissolves readily in water, yet shows negligible solubility in alcohol. Thermal properties should be noted in handling: it begins to dehydrate and lose crystal water at 60°C. Proper sealed, cool storage is recommended to prevent moisture variation and particle agglomeration.
It possesses diversified industrial utilization scenarios. It is applied within pharmaceutical raw material processing, formulation of dry colors and pigment systems, and manufacturing of industrial explosives. Moreover, it acts as a classic analytical reagent widely utilized for chemical analysis, metal finishing and other fine chemical processes.
