Morin hydrate is widely used in biochemical research as a fluorescent probe due to its ability to bind with metal ions, particularly aluminum and iron. This property makes it valuable for detecting and quantifying these ions in various samples. It is also employed in studies related to antioxidant activity, as morin hydrate exhibits free radical scavenging properties, helping to understand oxidative stress mechanisms. Additionally, it is used in histology for staining tissues, aiding in the visualization of cellular structures under a microscope. In pharmacology, morin hydrate is investigated for its potential therapeutic effects, including anti-inflammatory, anticancer, and antimicrobial properties, contributing to the development of novel drugs.
