Scopolin is primarily used in pharmaceutical research due to its biological activity. It serves as a marker compound in the study of plant metabolism, especially in species that produce tropane alkaloids. Its presence helps in assessing the biosynthetic pathways and quality control of medicinal plants like those in the Solanaceae family. Scopolin also exhibits antioxidant properties, making it of interest in developing natural antioxidants for therapeutic use. Additionally, it has been investigated for its potential anti-inflammatory and neuroprotective effects, supporting its role in the development of drugs targeting neurological disorders.
