3,4-diacetoxystyrene can serve as a fluorescent or linking group and participate in the synthesis of various anti-tumor drugs. For example, it can promote tumour cell death by binding to DNA or serve as a fluorescent probe for tumour cell imaging. 3,4-diacetoxystyrene plays an essential role in the synthesis of anti-inflammatory drugs. It can serve as a structural template for osteoporosis drugs, enhancing their anti-inflammatory activity by modifying their substituents or introducing double bonds.
