Acetonitrile Structural Formula
Acetonitrile is an aliphatic nitrile and a volatile organic compound. Acetonitrile is less dense than water and its vapour is dense than air (Vapor pressure = 9.71 kPa). The structural formula of Acetonitrile is as shown below in the diagram.
Applications Of Acetonitrile
- Because of a high dielectric constant and capable to dissolve electrolytes acetonitriles are mainly used in battery applications.
- It is used in high-performance liquid chromatography (HPLC).
- It is used as a solvent in the manufacturing of DNA oligonucleotides, in a pharmaceutical field and in photographic film.
