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 functionalized dioxane ring system enables structural optimization for improved metabolic stability and bioavailability in drug candidates. Also employed in the preparation of chiral ligands and catalysts for asymmetric synthesis. Additionally, it serves as a building block in agrochemicals for designing herbicides and fungicides with enhanced environmental profiles.
