Description

Dicyclohexyltin Dibromide is a versatile organotin compound with the CAS number 2954-94-1, primarily valued as a key intermediate and catalyst in advanced organic synthesis. Its structure makes it particularly effective for facilitating specific coupling and polymerization reactions. This chemical is essential for R&D and production in the fine chemical, pharmaceutical, and polymer industries, where precise catalytic activity is required.

Application

• Catalyst in polyurethane (PU) foam production and other polymerization processes.
• Key intermediate for synthesizing more complex organotin stabilizers and biocides.
• Used in cross-coupling reactions, such as Stille couplings, for creating carbon-carbon bonds in pharmaceutical research.
• Precursor material for the development of novel tin-based catalysts with tailored properties.
• Employed in organic synthesis laboratories for the study of organometallic reaction mechanisms.
• Potential use in the manufacture of PVC heat stabilizers, although less common than other tin derivatives.
