FAQs

Question: What chemical is potassium hexacyanoferrate(III)?

Answer:It is potassium ferricyanide, K₃[Fe(CN)₆], CAS 13746-66-2, with a molar mass of 329.25 g/mol.

Question: Which quality grade and package are supplied?

Answer:The 250 g plastic bottle contains EMSURE for-analysis material meeting the stated ACS and Reag. Ph Eur grade designations.

Question: Which handling precaution is especially important?

Answer:Avoid contact with strong acids and follow the safety data sheet; decomposition can release hazardous hydrogen cyanide.

Application Note

Potassium hexacyanoferrate(III), also called potassium ferricyanide, is an inorganic oxidizing reagent used in analytical chemistry and redox-based reactions. The crystalline material has the molecular formula K₃[Fe(CN)₆], a molar mass of 329.25 g/mol and CAS number 13746-66-2. EMSURE analytical-grade material is specified for analysis under ACS and Reag. Ph Eur requirements. This package contains 250 g in a plastic bottle. Prepare aqueous working solutions using the concentration required by the validated method and protect reagents from avoidable contamination. In redox assays, reaction pH, reagent concentration and the presence of reducing substances affect the response and should be controlled by calibration or procedural standards. Keep the reagent away from strong acids: decomposition can generate hazardous hydrogen cyanide. Handle solids and solutions with appropriate protective equipment, consult the current safety data sheet, and dispose of residues as regulated chemical waste. Lot-specific quality data are available through the manufacturer's certificate of analysis.
