Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. Its structure supports the creation of bioactive molecules with improved metabolic stability and receptor binding. Commonly employed in medicinal chemistry for constructing dioxane-fused ring systems found in antidepressant and anxiolytic drugs. Also utilized in research settings to explore new therapeutic compounds targeting neurological disorders.
