Potassium Ferrocyanide Supplier in Malaysia
- Also known as
- Potassium hexacyanoferrate(II)
- Yellow Prussiate of Potash
- K4[Fe(CN)6]
Potassium ferrocyanide supplier enquiries in Malaysia cover food, technical and laboratory requirements. Also called potassium hexacyanoferrate(II), yellow prussiate of potash and K4[Fe(CN)6], it is a pale yellow crystalline salt whose grade and hydration state should be stated in the purchasing specification.
Commercial options include food grade for enquiries that name E536, technical material for pigment or specialist process chemistry, and reagent grade for analytical work. The trihydrate is a common commercial form, but buyers should confirm hydration state rather than assume every grade has the same basis.
Food processors, pigment manufacturers and specialist metal-treatment users specify the ferrocyanide complex for different duties. Laboratories use it in defined analytical and coordination-chemistry methods. It is distinct from potassium ferricyanide and from free potassium cyanide.
Send the required grade, hydration state, specification, application, quantity and delivery location with your enquiry. Availability, packing, documentation and delivery timing are confirmed with the quotation, subject to applicable requirements.

Potassium Ferrocyanide grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Food grade potassium ferrocyanide | pale yellow crystals or crystalline powder | — | Food-processing applications that specifically name potassium ferrocyanide or E536 as the required processing input. State the applicable product specification and documentation requirement with the enquiry. | Confirm the required pack format with the quotation. |
| Technical potassium ferrocyanide | pale yellow crystals or powder | — | Pigment and colour chemistry, specialist metal-treatment processes and other industrial duties where the ferrocyanide complex and impurity profile are defined by the process specification. | Confirm the required pack format with the quotation. |
| Reagent grade potassium ferrocyanide | fine pale yellow crystalline powder | — | Analytical, laboratory and controlled synthesis work requiring a defined potassium hexacyanoferrate(II) identity and tighter purity controls. | Confirm the required pack format with the quotation. |

Common questions about potassium ferrocyanide
Is potassium ferrocyanide the same as potassium hexacyanoferrate(II)?
Yes. Potassium ferrocyanide is the common name for potassium hexacyanoferrate(II), also known as yellow prussiate of potash. The commercial grade may be specified as a hydrate, so state the required form and specification with the enquiry.
Is potassium ferrocyanide the same as potassium ferricyanide?
No. Potassium ferrocyanide is the iron(II) complex K4[Fe(CN)6], whereas potassium ferricyanide is the iron(III) complex K3[Fe(CN)6]. They are related but distinct products with different redox behaviour and applications.
Is potassium ferrocyanide the same as potassium cyanide?
No. Potassium ferrocyanide is a coordinated iron-cyanide complex, while potassium cyanide is the separate salt KCN. They must not be treated as aliases or substituted by name in a purchasing specification.
What is yellow prussiate of potash or E536?
Yellow prussiate of potash is a common name for potassium ferrocyanide, and E536 is the food-additive identifier used when a food grade is specified. Food, technical and reagent grades remain separate purchasing options, so state the intended use and required specification.
Which potassium ferrocyanide grade should I request?
Food grade is selected when the food process names E536, technical grade serves industrial pigment or specialist process work, and reagent grade is used for analytical or controlled laboratory methods. Provide the method, assay, hydration state and impurity limits with the enquiry.
What details are needed for a potassium ferrocyanide quotation?
Provide the grade, hydration state, assay or purity basis, application, quantity and delivery location. Mention preferred packing and any required food, quality or safety documents so they can be considered in the quote.
