Description

Sudan III Certified CAS: 85-86-9 | MF: C22H16N4O | MW: 352.39, Buy Histological Stains & Dyes for Histology, Cytology, Microbiology, Hematology & Biology Lab from TriStains.

Sudan III Certified (CAS No. 85-86-9) is a high-purity synthetic azo dye that is extensively used in the laboratory and industrial sectors. As one of the Sudan dye family, this compound is particularly known to have a good affinity for fats and oils. Having a molecular formula of C22H16N4O and a molecular weight of 352.39 g/mol, Sudan III Certified has been used as a lipid-containing material for histological stain. Sudan III on biological samples gives a characteristic reddish-orange coloration in complex lipids in their structure and, therefore, can be viewed microscopically and analyzed 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: Stains frozen tissue sections with fat cells and allows lipid distribution and fat accumulation to be studied in detail.
  • Lipid Staining: Stains neutral lipids, triglycerides and cholesterol esters in cells and biological tissues effectively.
  • Synthetic Fiber Textile Dyeing: Used in selective textile processes to color synthetic fibers and specialty fabrics.
  • Research and Industrial Use: Used to trace and color things in laboratory studies and monitor situations in industry.

Key features

  • Selective Lipid Staining: Shows great affinity to fats and oils, and gives sharp and distinct staining when observed under a microscope.
  • Bright, Deep Reddish-Orange Color: Increases contrast to enable easy recognition of lipid-rich structures and materials.
  • Qualified Laboratory Quality: Produced and approved as scientific grade, very pure, consistent, and reliable.
  • Multi-Disciplinary Applications: Applicable in the laboratory context, analytical chemistry and biological sciences, textile industries and research sectors.

General Description

Sudan III Certified (CAS 85-86-9) is a high-quality lipid staining stain in the form of a premium-grade lipid stain dye. This dye has a molecular weight of 352.39 grams per mole (gm/mol) and a molecular formula of C22H16N4O, which makes the dye a powerful lipid and fat-soluble interacting molecule. Sudan III, being a part of the Sudan dye series, gives the lipid-containing tissues a strong reddish-orange stain and, as a result, is used to provide a crucial stain in histology, cytology, microbiology, and hematology laboratories. It is highly depended to detect lipids accurately and conducting research with precision.

TECHNICAL INFORMATION
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)
CAS Number 85-86-9
Molecular Weight 352.39
Molecular Formula C22H16N4O

* Refer to Certificate of Analysis for lot specific data (including water content).

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.

TECHNICAL INFORMATION
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.
