GENERAL DESCRIPTION & APPLICATIONS

Sudan is a group of solvent dye, frequently called lysochrome (Lyso- means dissolving and -chrome means colour). In structural classification, sudan belongs to diazo dye. Azo colorant molecule can be described as aryl-N=N-R, where R is aryl, heteroaryl or -CH=C(OH)-. Solvent dyes are insoluble in water but soluble in nonpolar organic solvents and fats. It is usually used as a solution in an organic solvent. Azo structure solvent dyes are often responsible yellow-red color whereas anthraquinone structure solvent dyes tend to be green-blue. Some other structures for solvent dyes include heterocyclic rings, metal complex, pyrazolone, xanthene, and ketoamine. Solvent dyes do not ionise. Solvent dye, undergoing molecular rearrangement, is dissoluted in the substrate. It colours and binds to the lipids resulting in showing colored regions. In industrial field, it is used in coloring oils, waxes, greases, fats, hydrocarbons derivatives, polishes, oily insecticides, and acrylic emulsions. Sudans are used for demonstrating fats, triglycerides and lipoproteins present in tissues as biological stains.
