Acetonitrile
Acetonitrile, often abbreviated MeCN, is the chemical compound with the formula CH3CN and structure H3C−C≡N.
This colourless liquid is the simplest organic nitrile. It is produced mainly as a byproduct of acrylonitrile manufacture.

USE : Unlike the other common ketone solvents, acetone and MEK, MIBK has quite low solubility in water, making it useful for liquid-liquid extraction. It has a similar polarity to ethyl acetate, but greater stability towards aqueous acid and base.
