| General description: | Tin(IV) tert-butoxide (Sn(OtBu)₄) is an organotin compound available with a high purity of ≥99.99% trace metals basis. It serves as a precursor for the synthesis of tin oxide (SnO₂) thin films and nanostructures. Its volatility and thermal decomposition make it ideal for chemical vapor deposition (CVD) and atomic layer deposition (ALD), enabling the production of SnO₂ coatings used in gas sensors and optoelectronic devices. Additionally, it is employed in the synthesis of tin oxide nanoparticles and nanowires, which are utilized in catalysis, energy storage, electronics, and sensor technologies. |
