Eriochrome Black A

CAS: 3618-58-4

Eriochrome Black A is a dye that absorbs light in the near-infrared region. It is used as an indicator for thermal expansion and water vapor, and has been shown to be effective against infectious and inflammatory diseases. Eriochrome Black A forms a complex with metal ions such as iron or copper, which can be chelated by hydroxyl groups. This complex is then able to bind to cellular receptors, which causes an increase in oxidative stress, leading to cell death. Eriochrome Black A has also been shown to have antioxidant properties, which may be due to its ability to scavenge free radicals.
