Ceplignan is primarily used in the pharmaceutical industry as an intermediate in the synthesis of bioactive compounds. It exhibits potential antioxidant and anti-inflammatory properties, making it valuable in the development of therapeutic agents targeting oxidative stress-related conditions. Research has explored its application in neuroprotective drugs due to its ability to cross the blood-brain barrier and modulate cellular defense mechanisms. Additionally, Ceplignan has been investigated for use in cosmetic formulations for skin protection against environmental damage. Its structural features allow for derivatization into more complex molecules, supporting its role in drug discovery and functional material design.
