2. any organic compound containing one or more hydroxyl groups attached to an aromatic or carbon ring.
a measure of the bactericidal activity of a chemical compound in relation to phenol. The activity of the compound is expressed as the ratio of dilution in which it kills in 10 minutes under specified conditions. It can be determined in the absence of organic matter, or in the presence of a standard amount of added organic matter.
a sensitive, colorimetric method for estimating the protein content of cerebrospinal fluid.
includes gossypol, tannins.
animals can be exposed to phenol by skin contact with floors and housing which have been treated with the disinfectant, or other phenol-rich substance such as lignite pitch, or by nibbling at wood treated with it. Causes local tissue necrosis and hepatic injury. Cats are particularly susceptible.
