Used as a catalyst in organic synthesis, particularly in esterification and transesterification reactions. It is effective in the production of biodiesel from vegetable oils due to its ability to promote methanolysis with high efficiency and selectivity. Also employed in the preparation of metal oxide films and coatings through sol-gel processes, where it acts as a precursor for calcium-containing materials. Its reactivity with moisture and alcohols makes it useful in promoting condensation reactions in specialty polymer formulations.
