Product Description:

Indigo carmine, also known as 5,5′-indigodisulfonic acid sodium salt, is a water-soluble organic compound derived from indigo through aromatic sulfonation. It produces a vivid blue color and is widely used across multiple industries, including food, cosmetics, pharmaceuticals, and medical diagnostics. In medicine, indigo carmine serves as a contrast and staining agent, helping visualize structures during surgical and urological procedures, and it also functions as a pH and redox indicator.

In aqueous solutions, indigo carmine exhibits distinct color changes depending on the pH, appearing blue at pH 11.4 and turning yellow at pH 13.0. It also acts as a redox indicator, changing color upon reduction, and is used as a dissolved ozone indicator through its conversion to isatin-5-sulfonic acid, although it can also detect superoxide. Beyond its diagnostic applications, indigo carmine is employed as a dye in the manufacturing of pharmaceutical capsules, ensuring vibrant and consistent coloration. Approved for human use in the United States and European Union, indigo carmine is a versatile compound that combines functional utility with safe application in clinical and industrial settings.
