    Description

    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.
