Note: It has a peculiar odor, somewhat resembling creosote,
which is a complex mixture of phenol derivatives. It is
of the type of alcohols, and is called also {phenyl

popularly called carbolic acid, and was formerly
called phenic acid. It is a powerful caustic poison,
and in dilute solution has been used as an antiseptic.
