Guanidine is the compound with the formula HNC(NH 2) 2. It is a colourless solid that dissolves in polar solvents. It is a strong base that is used in the production of plastics and explosives .
Guanidinium chloride is a weak acid with a pK a of 13.6. The reason that it is such a weak acid is the complete delocalisation of the positive charge through 3 nitrogen atoms (plus a little bit positive charge on carbon).
p-Phenylenediamine (PPD) is an organic compound with the formula C 6 H 4 (NH 2) 2. This derivative of aniline is a white solid, but samples can darken due to air oxidation. [1] It is mainly used as a component of engineering polymers and composites like kevlar. It is also an ingredient in hair dyes and is occasionally used as a substitute for ...

Tetramethylguanidine is an organic compound with the formula HNC(N(CH 3) 2) 2. This colourless liquid is a strong base, as judged by the high pK a of its' conjugate acid. [2] It was originally prepared from tetramethylthiourea via S-methylation and amination, but alternative methods start from cyanogen iodide. [3]
A carbonate is a salt of carbonic acid, (H 2 CO 3), [2] characterized by the presence of the carbonate ion, a polyatomic ion with the formula CO 2− 3. The word "carbonate" may also refer to a carbonate ester , an organic compound containing the carbonate group O=C(−O−) 2 .
