  • Applications

    Butylstannonic acid (CAS 2273-43-0) is an organotin building block and intermediate commonly used in organotin chemistry. In practical terms, it may be employed to prepare tin-containing derivatives that function as catalysts for polymerization and as precursors to tin-based stabilizers for polymers and coatings. It is also evaluated as a starting material for tin-based additives used in coatings and inks, and as a reagent for synthesizing other organotin compounds intended for electronics-related applications such as thin films or conductive materials. Additionally, it serves as a source of tin in research and development for creating new catalysts and functional additives.
