Related to Benzanol: benzoyl
1. an extremely poisonous compound, used in dilute solution as an antimicrobial, anesthetic, and antipruritic. Ingestion or absorption through the skin causes symptoms including colic, local irritation, corrosion, seizures, cardiac arrhythmias, shock, and respiratory arrest. Phenol should be properly labeled and stored to avoid accidental poisoning. Called also carbolic acid.
2. any of various related organic compounds containing one or more hydroxyl groups attached to an aromatic carbon ring.
phenol coefficient 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 but not in 5 minutes under the specified conditions. It can be determined in the absence of organic matter, or in the presence of a standard amount of added organic matter.

phenolcarbolic acid, C6H5OH, which has been used as an antiseptic and DISINFECTANT because of its antimicrobial activity. However, it irritates the skin and so is rarely used for such purposes nowadays. Derivatives of phenol, called phenolics, contain a molecule of phenol that has been altered chemically to reduce its ability to irritate and/or to increase its antimicrobial activity. Phenolics act by damaging PLASMA MEMBRANES, inactivating ENZYMES and denaturing PROTEINS (see DENATURATION). Phenolics include cresols, which are good surface disinfectants, and hexachlorophene, which is used to control NOSOCOMIAL INFECTIONS.
