Description
Acetonitrile HPLC grade is a clear, colorless liquid with an ether-like odor and a sweet, burnt taste. It is often abbreviated Methyl Cyanide(MeCN). Its chemical formula is CH₃CN and structure is H₃C−C≡N. It is produced mainly as a byproduct of acrylonitrile manufacture. Acetonitrile HPLC solvent is free from UV-absorbing impurities that ensures consistent result in gradient analysis with noise-free baselines and minimum drift.
