It is commonly found in natural sources such as plants and rocks, but it can also be produced artificially by the reaction of sulfuric acid with potassium permanganate (KMnO4) to produce purple or blue compounds. Sulphocyanogen has many industrial applications, including as a pigment in paints and dyes, as a fertilizer, and as a colorant in food coloring.
