Used as a catalyst in various organic synthesis reactions, particularly in the production of polymers and resins. It is also employed in the preparation of metal oxide thin films and coatings through chemical vapor deposition (CVD) and sol-gel processes. Additionally, it serves as a precursor in the synthesis of other tin-containing compounds, which are utilized in materials science and nanotechnology applications. Its role in facilitating esterification and transesterification reactions makes it valuable in the production of biodiesel and other ester-based products.
