Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of serotonin receptor agonists and antagonists. It serves as a building block in the preparation of bioactive molecules due to its rigid dioxane-fused aromatic structure, which can enhance binding selectivity and metabolic stability. Commonly employed in medicinal chemistry for constructing benzodioxole-containing compounds with potential neurological activity. Also utilized in the design of fluorescent probes and functional materials owing to its electron-rich framework.
