Phenol (also known as carbolic acid, phenolic acid, or benzenol) is an aromatic organic compound with the molecular formula C 6 H 5 OH. [5] It is a white crystalline solid that is volatile . The molecule consists of a phenyl group ( −C 6 H 5 ) bonded to a hydroxy group ( −OH ).
Aromatic alcohols (example: tyrosol) are produced by the yeast Candida albicans. [47] They are also found in beer. [48] These molecules are quorum sensing compounds for Saccharomyces cerevisiae. [49] Metabolism. Aryl-alcohol dehydrogenase uses an aromatic alcohol and NAD + to produce an aromatic aldehyde, NADH and H +.
In organic chemistry, phenols, sometimes called phenolics, are a class of chemical compounds consisting of one or more hydroxyl groups (−O H) bonded directly to an aromatic hydrocarbon group. [1] The simplest is phenol, C 6 H 5 OH. Phenolic compounds are classified as simple phenols or polyphenols based on the number of phenol units in the ...
Included in that class are substances containing a phenolic ring and an organic carboxylic acid function (C6-C1 skeleton). Two important naturally occurring types of phenolic acids are hydroxybenzoic acids and hydroxycinnamic acids, which are derived from non-phenolic molecules of benzoic and cinnamic acid, respectively.

In chemistry, an alcohol (from Arabic al-kuḥl 'the kohl'), [2] is a type of organic compound that carries at least one hydroxyl (−OH) functional group bound to a saturated carbon atom. [3] [4] Alcohols range from the simple, like methanol and ethanol, to complex, like sugars and cholesterol. The presence of an OH group strongly modifies the ...
The mixture of nonylphenol isomers is a pale yellow liquid, although the pure compounds are colorless. The nonylphenols are moderately soluble in water [12] but soluble in alcohol. Nonylphenol arises from the environmental degradation of nonylphenol ethoxylates, which are the metabolites of commercial detergents called alkylphenol ethoxylates ...

Phenol is the standard, and the corresponding rating system is called the "Phenol coefficient". The disinfectant to be tested is compared with phenol on a standard microbe (usually Salmonella typhi or Staphylococcus aureus). Disinfectants that are more effective than phenol have a coefficient > 1. Those that are less effective have a ...
