Morin hydrate is widely used in biochemical research as a fluorescent dye for detecting and quantifying metal ions, particularly aluminum and iron, due to its strong chelating properties. It serves as a vital tool in studying oxidative stress and antioxidant mechanisms, as it can scavenge free radicals and inhibit lipid peroxidation. In histology, it is employed as a staining agent to visualize cellular structures and tissues under a microscope. Additionally, it has potential applications in pharmaceuticals, where its anti-inflammatory, anticancer, and antimicrobial properties are being explored for therapeutic development. Its ability to modulate enzyme activity also makes it valuable in enzymatic studies and drug discovery research. Emerging studies suggest potential uses in food preservation as an antioxidant and in cosmetics for UV protection, though primary applications remain in laboratory settings.
