Sinapic acid is widely used in the food industry as a natural preservative due to its antioxidant properties, helping to extend the shelf life of products by preventing oxidation. In the pharmaceutical sector, it is studied for its potential anti-inflammatory, anticancer, and neuroprotective effects, making it a promising candidate for developing therapeutic drugs. Additionally, sinapic acid is utilized in cosmetic formulations for its ability to protect the skin from UV-induced damage and its role in reducing oxidative stress, contributing to anti-aging benefits. Its applications also extend to agriculture, where it is explored as a natural pesticide to protect crops from pathogens.
