Scopoletin is widely used in pharmaceutical and cosmetic industries due to its biological activities. It exhibits anti-inflammatory and antioxidant properties, making it valuable in formulations aimed at reducing skin irritation and aging. It is also studied for its potential in managing neurodegenerative diseases because of its ability to cross the blood-brain barrier and protect neural cells from oxidative stress. In agriculture, scopoletin acts as a natural phytoalexin, helping plants defend against pathogens and environmental stress, which supports its use in developing bio-based crop protection agents. Additionally, it serves as a marker compound in quality control of medicinal plants, especially in traditional herbal medicines.
