| Tetramethylguanidine Usage And Synthesis |
| Chemical Properties | Liquid | | Uses | Tetramethylguanidine (TMG) is used as polyurethane foam catalyst, as accelerator for the syntheses of polysulfured rubber, as a strong base in the photochemical (e.g. couplers) and in the pharmaceutical (e.g. steroids) industries. Product Data Sheet | | Uses | Base employed in the preparation of alkyl nitriles from alkyl halides and 3′-alkylthymidines from 3′-nitrothymidines. | | Uses | 1,1,3,3-Tetaramethylguanidine is used as a strong, non-nucleophilic base for alkylations in organic synthesis. 1,1,3,3-Tetramethylguanidine is an efficient and selective catalyst for the benzoylation
of alcohols. | | Flammability and Explosibility | Flammable | | Purification Methods | Reflux it over granulated BaO, then fractionally distil it. Protect it from CO2. [Beilstein 4 IV 227.] |
