GENERAL DESCRIPTION OF QUINOLINE and APPLICATIONS
Quinoline, hygroscopic, yellowish oily liquid, is an aromatic nitrogen compound characterized by a double-ring structure contains a benzene and a pyridine. (Pyridine is a ring structure compound of five carbon atoms with a nitrogen atom). These two rings are fused at two adjacent carbon atoms. Quinoline itself is the simplest member of the quinoline. It can be prepared by the distillation of coal tar or by synthesis from aniline. It is soluble in water as well as in alcohol, ether, and carbon disulfide. Isoquinoline differs from quinoline in nitrogen position. Quinoline family compounds are widely used as a parent compound to make drugs (especially anti-malarial medicines), fungicides, biocides, alkaloids, dyes, rubber chemicals and flavoring agents. They have antiseptic, antipyretic, and antiperiodic properties. They are also used as catalyst, corrosion inhibitor, preservative, and as solvent for resins and terpenes. They are used in transition-metal complex catalyst chemistry for uniform polymerization and luminescence chemistry.

The prefix nitro- indicates the presence of NO2- radical, while nitrate refers to any salt or ester of nitric acid or the NO3- anion. Nitroso- is the prefix indicating presence of the group -NO and azo- is for -N=N- group. Some range of  organic compounds containing nitrogen include nitro compounds (RNO2 ), nitroso compounds (RNO), amines (R3N ), amino acids, and natural alkaloids or nucleotides. The nitrogen ion in nitro compounds is trigonally planar with 120° angles. There are two resonance bonds so that the two oxygens are equivalent. Nitro compounds are strongly basic due to electron withdrawing both inductively and mesomerically. Historically, they are abundant in dyes and explosives. Nitro compounds, organic hydrocarbons having one or more NO2 groups bonded via nitrogen to the carbon framework, are versatile intermediate in organic synthesis.

Nitro compounds are readily reduced into amines when reacted with hydrochloric acid. Aromatic nitro compounds also yield anilines, aromatic amine componds. Nitro compounds are cleaved into two parts by the addition of a molecule of water to produce carbonyl compounds (aldehydes or ketones). Aromatic nitro compounds undergo nucleophilic substitutions to be replaced by the hydroxide anion, resulting in the creation of phenol compounds and by alkoxy nucleophiles to corresponding ethers.
