|Section2= |Section3= |Section4= }} Tetramethylguanidine is an organic compound with the formula HNC(N(CH3)2)2. This colourless liquid is a strong base with a higher pKa than typical amines. It was originally prepared from tetramethylthiourea via ''S''-methylation and amination, but alternative methods start from cyanogen iodide. ==Uses== TMG is mainly used as a strong, non-nucleophilic base for alkylations, often as a substitute for the more expensive bases DBU and DBN.〔 Since it is highly water-soluble, it is easily removed from mixtures in organic solvents. It is also used as a base-catalyst in the production of polyurethane.
