IDH, scientifically known as indoline-5,6-diol hydrobromide, is an extensively utilized organic compound in the domains of organic synthesis, pharmaceuticals, and biochemistry. Serving as a crucial foundational component for synthesizing diverse compounds, IDH finds widespread applications across multiple fields. It manifests as a colorless, crystalline solid with hygroscopic properties and demonstrates solubility in water and ethanol. Alternate names for IDH include 5-bromo-4-indoline-2-diol or 5-bromo-4-hydroxy-2-indoline. Researchers propose that IDH operates as an inhibitor of enzymes, effectively impeding their activity. Moreover, IDH exhibits antioxidant qualities by effectively scavenging free radicals and providing protection against oxidative damage.
5,6-Dihydroxyindoline hydrobromide is commonly used in cosmetics as a hair colouring agent, but also in hair care or hairdressing cosmetics research.
