Cerium acetate is a specialty chemical primarily used as a precursor for the synthesis of cerium oxide (CeO₂) nanoparticles and thin films, which are applied in catalysis, polishing compounds, and UV-absorbing materials.

It serves as a reagent in organic synthesis, particularly for ceric ammonium nitrate (CAN)-type oxidations after conversion.

Investigated for antimicrobial properties in wound dressings and biomedical applications, though less common than cerium nitrate.

Employed in the production of specialty glasses and ceramics to enhance optical properties and thermal stability.

Explored in fuel cell electrolytes and as a catalyst support in pollution control systems.
