Used as a key intermediate in the synthesis of vitamin D analogs and related steroidal compounds. Its functionalized cyclohexylidene backbone with protected hydroxyl groups allows selective deprotection and further chemical modifications, making it valuable in pharmaceutical research, particularly in developing drugs targeting metabolic and hormonal disorders. The silyl protecting groups enhance stability and solubility during multi-step syntheses, while the exocyclic methylene and alkene alcohol moieties enable coupling reactions and ring transformations essential for constructing complex steroid-like structures.
