pyridine
Six-membered aromatic base
Pyridine is a colorless liquid with a sharp, unpleasant odor, used as a solvent and in manufacturing pharmaceuticals, pesticides, and other chemicals.
It's a six-membered ring compound similar to benzene but with one nitrogen atom replacing a carbon—a basic structure that appears throughout organic chemistry and biochemistry.
The lab smelled strongly of pyridine.
