| Description | Dye Content: ≥ 95% (dried basis). Indigo carmine, or 5,5'-indigodisulfonic acid sodium salt, also known as indigotine or FD&C Blue #2, is a pH indicator with the chemical formula C16H8N2Na2O8S2. It is approved for use as a food colorant in the United States[2] and in Europe.[3] and has the E number E132. Indigo carmine is commonly used as a pH indicator, often in a 0.2% aqueous solution. It is blue at pH 11.4 and yellow at 13.0. Indigo carmine is also a redox indicator, turning yellow upon reduction. Another use is as a dissolved ozone indicator[4] through the conversion to isatin-5-sulfonic acid.[4] This reaction has been shown not to be specific to ozone, however: it also detects superoxide, an important distinction in cell physiology.[5] It is also used as a dye in the manufacturing of capsules. In obstetric surgery, indigo carmine solutions are sometimes employed to detect amniotic fluid leaks. In urologic surgery, intravenous injection of indigo carmine is often used to highlight |
