Fenol

Phenol is an aromatic organic compound with the molecular formula C6H5OH.
It is a volatile, white crystalline solid.
Phenol causes chemical burns and therefore must be handled with care.
The sodium salt of phenol, sodium phenoxide, is much more soluble in water than phenol itself.

It is an essential industrial raw material as a precursor to various materials and useful compounds.
It is primarily used in the synthesis of plastics.
Phenol and its chemical derivatives are necessary for the manufacture of a wide range of pharmaceutical drugs, including polycarbonates, epoxies, Bakelite, nylons, detergents, and phenoxy herbicides.
Phenol was historically used as an antiseptic, a practice pioneered by Joseph Lister.
For a long period starting in the early 20th century, it was used in the production of carbolic soap.
Concentrated phenol liquids are also frequently used in the medical field for the permanent treatment of ingrown toenails and fingernails.
