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
alcohol}, but has acid properties, and hence is
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.
[1913 Webster]
2. Any one of the series of hydroxyl derivatives of which
phenol proper is the type.

Phenol acid (Chem.), any one of a series of compounds which
are at once a derivative of phenol and an organic acid;
thus, salicylic acid is a phenol acid.
Phenol alcohol (Chem.), any one of series of derivatives of
phenol and carbinol which have the properties of both
