  • Applications

    Dioxogermane, CAS 1310-53-8, is primarily used as a precursor and source of germanium for organogermanium chemistry; as a precursor for Ge-oxide coatings and Ge-containing films in electronics and optics; as a feedstock for Ge-containing polymers and specialty ceramic materials; evaluated for use in specialized coatings and thin-film applications and as a research starting material to develop other germanium-containing compounds.
