APPLICATIONS
Pyrazine, hygroscopic white solid, is an aromatic nitrogen compound characterized by a ring structure contains  4 carbon atoms with two nitrogen atoms at 1 and 4 positions (paradiazine); melting at 55 - 56 C, boiling at 115 - 116 C. Pyrazine is freely soluble in water. It is fused to form many polycyclic compounds, as useful structures in pharmaceuticals and perfumes. It is a component of the folates (vitamin B compounds) and of the isoalloxazine ring nucleus of flavins. Numerous pyrazine derivatives such as pyrazine polycyclic compounds, alkyl-, alicyclic-, and alkylaryl-substituted compounds, derivatives containing oxygenated functional groups and thio- functional groups in the side-chains are used in biological, drug, flavouring and perfumery industry.

Nitrile is any of a family of organic compounds containing cyano group (-C≡N) which is attached to a carbon atom and having the general formula RC≡N. Their names are corresponding to carboxylic acids by changing '-ic acid' to '-onitrile', or '-nitrile', whichever preserves a single letter o. Examples are acetonitrile from acetic acid and benzonitrile from benzoic acid. Pendant nitriles are often named as “cyano” substituents.
