Sudan III Certified (CAS No. 85-86-9) is a well-known synthetic azo dye of high purity that finds extensive use in laboratory and industrial practices. This compound, being a part of the Sudan dye family, is particularly known to be very attracted to fats and oils. Sudan III Certified has a molecular formula of C22H16N4O and a molecular weight of 352.39 g/mol and is mostly used as a lipid-based histological stain. When used on biological samples, the Sudan III turns the structurally complex lipids to a characteristic reddish-orange colouration, which can be easily seen under a microscope and further examined in detail. This certified dye is also used in the coloration of textiles, as well as in some industrial marking processes, in addition to the histological and cytological applications.
Applications
- Histology and Cytology: Stained on frozen tissue section containing fat cells so that the distribution of lipids and fat could be studied in depth.
- Lipid Staining: Stains the neutral lipids, triglycerides and cholesterol esters in the cell and the biological tissues effectively.
- Synthetic Fiber Textile Dyeing.: Used in restricted plumbing procedures in the coloration of synthetic fibers and fabrics of specialty.
- Research and Industrial Use: Find use in coloring and tracking a subject in research and controlled industrial settings.
Key features
- Selective Lipid Staining: Affinities to fats and oils are strong with sharp and well-defined staining on microscopic examination.
- Bright, Deep Reddish-Orange Color: Offers better contrast to facilitate the identification of lipid-rich structures and materials easily.
- Qualified Laboratory Quality: Produced and accredited as scientific grade, with high purity and consistency and reliability.
- Multi-Disciplinary Applications: Suited in the laboratory, in analytic chemistry, in the biological sciences, in the textile industries, and in research establishments.

| Alternate Names | Solvent Red 23; CI 26100 |
| Application | Sudan III is a lysochrome (fat soluble dye) predominantly used for staining triglycerides in animal tissues (frozen sections) |

Sudan III is predominantly used for staining triglycerides in animal tissues (frozen sections). Sudan dyes are a group of lipid soluble solvent dyes often called lysochromes, in structural classification they are diazo dyes. With the use of certain solvents, may also be used to stain some protein bound lipids in paraffin sections. Sudan I (sc-215922), Sudan III (sc-203761), and Sudan IV (sc-203762) have been classified as category 3 carcinogens by the International Agency for Research on Cancer.
| Usage | A saturated solution in isopropanol is prepared for use as a fat stain in animal tissue. Counterstain for 5 minutes in acid alum hematoxylin (approx. 0.1%). Fats will appear yellow orange in color and the nuclei will appear blue. The cytoplasm will appear green. Since lysochromes are soluble in non polar solvents, including xylene and toluene, and also in ethanol, these fluids must not be put on to sections after fats have been stained or the dye will be dissolved out; therefore resinous mounting media are not recommended. We recommend mounting sections with Crystal Mounting Medium; sc-24943. |
