Used primarily as a precursor in the synthesis of germanium-containing polymers and organogermanium compounds, which exhibit potential in semiconductor and optoelectronic applications. Its reactivity allows for incorporation into silicone-based materials to enhance thermal stability and electrical properties. Also explored in research for developing new germanium-based catalysts and bioactive agents due to the unique electronic characteristics of the germanium-chlorine and carboxy-functional groups. Handling requires caution due to moisture sensitivity and potential corrosivity.
