Welcome to inquire us to get the complete COA

Solvent Red 23 (Colour Index No. 26100), commonly known as Sudan III, is a synthetic azo dye derived from naphthalene. Its chemical structure features a characteristic azo group (–N=N–) linking aromatic rings, making it intensely colored and soluble in non-polar organic solvents.

Primary Uses in Chemical and Industrial Contexts:

1. Staining Agent in Biology & Histology: Its most famous use is as a lipophilic (fat-soluble) stain to identify and color lipids, triglycerides, and lipoproteins in frozen tissue sections and in biochemical assays (e.g., Sudan staining).

2. Industrial Colorant: It is used to dye non-polar materials such as hydrocarbon-based solvents, fuels, oils, waxes, and some plastics (e.g., polystyrene). Its "Solvent Red" name indicates this primary application.

3. Chemical Indicator & Tracer: Due to its strong color, it can be used as a visible tracer or flow marker in non-aqueous systems for laboratory or engineering demonstrations.

4. Model Compound in Chemistry: It serves as a classic example of an azo dye in organic chemistry education and research, particularly for studying synthesis, chromophores, and solubility principles.

Important Note:

It is not permitted for use in food, cosmetics, or pharmaceuticals in most regions due to potential toxicity and carcinogenicity. Its approved uses are strictly industrial and analytical.
