Used as a key intermediate in organic synthesis, particularly in the production of pharmaceuticals such as calcium channel blockers like diltiazem, which treats hypertension and angina. Its structure, featuring a cyclohexyl backbone with a reactive ketone and ester group, allows for further functionalization, making it valuable in constructing complex molecules for active pharmaceutical ingredients (APIs) and fine chemicals. Its reactivity profile supports use in carbonyl addition reactions, reductions, and condensation reactions under controlled conditions.
