Used primarily in organic synthesis, it serves as a key reagent for introducing germanium into organic molecules. It is particularly valuable in the preparation of organogermanium compounds, which find applications in materials science and catalysis. Additionally, it is employed in the development of semiconductors and optoelectronic devices due to its ability to modify electronic properties. It also plays a role in polymer chemistry, aiding in the creation of germanium-containing polymers with unique thermal and mechanical characteristics.
