What is the use of quinoline?
Quinoline is used principally for the manufacture of nicotinic acid, which prevents pellagra in humans, and other chemicals. Several methods are known for its preparation, and production of synthetic quinoline exceeds that from coal tar.
What is benzene used for?
It ranks in the top 20 chemicals for production volume. Some industries use benzene to make other chemicals that are used to make plastics, resins, and nylon and synthetic fibers. Benzene is also used to make some types of lubricants, rubbers, dyes, detergents, drugs, and pesticides.
Is pyridine an aromatic?
Pyridine is aromatic based on the following facts. The protons of pyridine display chemical shifts in the NMR spectrum that are typical of aromatic protons. The nitrogen of pyridine is sp2-hybridized and possesses one lone electron pair.
Is pyridine an antibiotic?
The presented work showed that the antibacterial activity of the studied pyridines depends on their structure and affects the LPS of bacteria. The obtained damage modification values of the analyzed compounds were compared with the modifications after antibiotics were used in this type of research.

How Does benzene cause leukemia?
Benzene has been shown to cause chromosome changes in bone marrow cells in the lab. (The bone marrow is where new blood cells are made.) Such changes are commonly found in human leukemia cells.
Why pyridine is more aromatic than thiophene?
Pyrrole has 4π electrons and the lonepair of electrons on the nitrogen participate in resonance with the ring to attain aromaticity. Therefore Pyridine is more aromatic than pyrrole.
Does azathioprine cause immunosuppression?
Azathioprine inhibits purine synthesis. Purines are needed to produce DNA and RNA. By inhibiting purine synthesis, less DNA and RNA are produced for the synthesis of white blood cells, thus causing immunosuppression.
