Potassium Ferrocyanide CAS 14459-95-1 powder granular

Potassium Ferrocyanide is an inorganic coordination compound widely used in various industrial and food fields. As a professional product for import purchasers, it has passed REACH registration, and MSDS download is available for safe use and compliance verification.

Product Aliases

Common aliases of Potassium Ferrocyanide include Potassium Hexacyanoferrate(II), Yellow Prussiate of Potash, and Tetrapotassium Hexacyanoferrate. These aliases are commonly used in different industrial scenarios and international trade, facilitating seamless communication between purchasers and suppliers.

Product Properties & Physical Characteristics

The appearance of Potassium Ferrocyanide is mainly light yellow powder and granular, which are the most common and stable forms for storage and transportation. Its molecular formula is K₄[Fe(CN)₆]·3H₂O (trihydrate form), which is stable under normal storage conditions.

Physical characteristics: It has a slight salty taste, a density of 1.85 g/cm³, and a melting point of 70℃. It is soluble in water (28.2 g/100g at 20℃) but insoluble in ethanol and ether. When heated to 70℃, it loses crystal water and turns white; it decomposes at high temperatures above 400℃, so proper storage is required.

Product Applications

Potassium Ferrocyanide has a wide range of applications across multiple industries, making it a high-demand product for import purchasers:

Food Industry: It is used as a legal anti-caking agent in table salt, preventing salt from clumping by converting the regular hexagonal crystals of salt into star-shaped crystals. It is compliant with international food safety standards, with a maximum allowable dosage of 10 mg/kg in salt.

Chemical Industry: It serves as a cyanide source in organic cyanation reactions, such as the cyanation of bromobenzene, improving the utilization rate of cyanide. It is also used as a raw material for the production of other chemicals like Prussian Blue (ferric ferrocyanide).

Analytical & Medical Testing: It is used as an analytical reagent, such as detecting the content of zinc oxide with diphenylamine as an indicator. It also plays a role in medical testing scenarios for specific substance detection.

Product Compliance

The product has completed REACH registration, fully complying with EU import and export regulations, which can effectively avoid customs clearance risks for import purchasers. MSDS download is provided to detail safety information, handling precautions, and emergency measures, ensuring safe use and transportation in line with international trade requirements.

FAQ

Q1: Is Potassium Ferrocyanide toxic and safe for use in food?

A1: Potassium Ferrocyanide is a low-toxic substance, with an oral LD50 (rat) of 1600~3200 mg/kg, similar to table salt. It is stable under normal cooking temperatures (below 340℃) and will not decompose into toxic cyanide. It is a legal food additive in the EU, US, Japan, and other regions, safe when used within the standard limit.

Q2: What is the shelf life of Potassium Ferrocyanide and how to store it properly?

A2: The shelf life is 24 months when stored in a sealed, cool, and dry environment, away from direct sunlight, acids, and oxidants. It should be kept in a well-ventilated warehouse to avoid dust diffusion, and sealed tightly after use to prevent moisture absorption and degradation.

Q3: Can Potassium Ferrocyanide be customized into other forms besides powder and granular?

A3: Currently, the main supply forms are powder and granular, which are the most stable and suitable for long-distance transportation and industrial application. Customization of other forms can be discussed based on specific purchase requirements and order volume.
