Used as a specialty intermediate in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. Its spirocyclic structure and functional groups make it valuable for constructing complex heterocyclic systems. The compound serves as a building block for sulfonamide and ether-based bioactive molecules, enabling the introduction of constrained ring systems that can enhance metabolic stability and binding selectivity in drug candidates. It is also employed in the synthesis of chiral auxiliaries and catalysts due to its rigid framework and stereochemical properties.
