Product Application: Tributyl(1-propynyl)tin can be used: As a starting material in the synthesis of phenyl-substituted pyrimidine-dione by reacting with ethyl isocyanate via cycloaddition and Stille coupling reactions. In the synthesis of 18F labeled triazolo quinoline derivative, a positron emission tomography (PET) ligand used in the in vivo imaging of metabotropic glutamate receptor type 1. In one of the key synthetic steps for the synthesis of 4-(1-aryltriazol-4-yl)-tetrahydropyridines as potent mGluR1 antagonists.
