Disperse Orange 3 is a diazonium salt that has been used in the textile industry as a dye, but has also been used as a reagent for the synthesis of organic compounds. Disperse Orange 3 is synthesized by reacting an azobenzene with a fatty acid, which yields an unstable intermediate. The intermediate undergoes photochemical reactions when exposed to ultraviolet light or moisture. This reaction produces benzalkonium chloride and ft-ir spectroscopy, which confirms the identity of Disperse Orange 3. Disperse Orange 3 is used in biological treatment and binding constants experiments to measure the strength of interactions between molecules. It has clinical relevance in magnetic resonance spectroscopy because it can be used to probe molecular interactions with proteins or nucleic acids. It also has solubility data that can be used to determine its solubility in water and other solvents. Disperse Orange 3 is soluble in supercritical carbon dioxide at high temperatures, but insoluble at room temperature.
