A colorless liquid with a chemical formula CH3CN, Acetonitrile is the
simplest organic nitrile. A byproduct of acrylonitrile manufacture, it is
mainly used as a polar aprotic solvent in purification of butadiene. Low in
acidity, acrylonitrile is used in laboratory as a medium-polarity solvent,
which is miscible with water and has a convenient liquid range. Acetonitrile
has a dipole moment [disambiguation needed] of 3.84 D and dissolves in a
wide range of ionic and non-polar compounds and is extremely useful as a
mobile phase in HPLC.

Acetone is the organic compound with the formula (CH3)2CO. This colorless,
mobile, flammable liquid is the simplest example of the ketones. Owing to
the fact that acetone is miscible with water it serves as an important
solvent in its own right, typically as the solvent of choice for cleaning
purposes in the laboratory.
CAS : 68-12-2
Dimethylformamide is the organic compound with the formula (CH3)2NC(O)H.
Commonly abbreviated DMF (though this acronym is sometimes used for
dimethylfuran), this colourless liquid is miscible with water and the
majority of organic liquids. DMF is a common solvent for chemical reactions.
Pure dimethylformamide is odorless whereas technical grade or degraded
dimethylformamide often has a fishy smell due to impurity of dimethylamine.
Its name is derived from the fact that it is a derivative of formamide, the
amide of formic acid.
