Quinoline is a heterocyclic aromatic organic compound with the chemical formula C9H7N.
Oxidation of quinoline with potassium permanganate yields quinolinic acid (pyridine-2, 3-dicarboxylic acid).
Quinoline is a colorless liquid, that darkens upon contact with air. It is not miscible with water, but more miscible with organic solvents. Its odor is similar to most amines, though not as unpleasant as pyridine.
Quinoline is sold by chemical suppliers.

Quinoline is irritant and should be handled with care.
In closed bottles, away from light and air.
Can be neutralized with Fenton's reagent.
Can also be destroyed by incineration in a special oven.
