Rupali Fine Chemicals manufactures Potassium Ferricyanide. Potassium Ferricyanide is the chemical compound. This is bright red salt. It is soluble in water and its solution shows some green-yellow fluorescence. The compound has widespread use in blueprint drawing and in photography [Cyanotype process]. Iron and copper toning involve the use of potassium ferricyanide. Potassium ferricyanide is used as an oxidizing agent to remove silver from negatives and positives, a process called dot etching. In color photography, potassium ferricyanide is used to reduce the size of color dots without reducing their number, as a kind of manual color correction. The compound is also used to harden iron and steel, in electroplating, dyeing wool, as a laboratory reagent, and as a mild oxidizing agent in organic chemistry. It is also used in photography with sodium thiosulfate [hypo][4] to reduce the density of a negative where the mixture is known as Farmer`s reducer; this can help offset problems from overexposure.
Rupali Fine Chemicals offers wide range of Pharmaceuticals, Chemicals & allied products. Potassium Ferricyanide is used in many amperometric biosensors as an electron transfer agent replacing an enzymes natural electron transfer agent such as oxygen as with the enzyme glucose oxidase. It is used as this ingredient in many commercially available blood glucose meters for use by diabetics.
