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 .
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]
Chemical formula. C 5 H 5 N 5 O Molar mass: 151.13 g/mol Appearance White amorphous solid. ... With the formula C 5 H 5 N 5 O, guanine is a derivative of purine, ...
In organic chemistry, the phenyl group, or phenyl ring, is a cyclic group of atoms with the formula C6H5, and is often represented by the symbol Ph (archaically φ) or Ø. The phenyl group is closely related to benzene and can be viewed as a benzene ring, minus a hydrogen, which may be replaced by some other element or compound to serve as a ...
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).
Guanidine nitrate is the chemical compound with the formula [C(NH 2) 3]NO 3. It is a colorless, water-soluble salt. It is a colorless, water-soluble salt. It is produced on a large scale and finds use as precursor for nitroguanidine , [ 1 ] fuel in pyrotechnics and gas generators .
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 ...
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 .
