Quinoline is a heterocyclic aromatic organic
compound. It has the formula C9H7N and is a
colourless to brown hygroscopic liquid with a strong
odour. Aged samples, if exposed to light, become
yellow and later brown. Quinoline is only slightly
soluble in cold water but dissolves readily in hot
water and most organic solvents.
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.
They are used as antifoaming agent in refinery
field. Quinaldine, 2-methylquinoline, is used as an
anti-malaria and preparing other anti-malaria drugs.
It is used in manufacturing oil soluble dyes, food
colorants, pharmaceuticals, pH indicators and other
organic compounds. Quinaldic Acid is a carboxylic
acid substituted quinoline at 2 position, a
catabolite of tryptophan (aromatic side chain amino
acid). Its principal use is as a precursor to
8-hydroxyquinoline, which is a versatile chelating
agent and precursor to pesticides. Its 2- and
4-methyl derivatives are precursors to cyanine dyes.
