Alkylphenols

Propofol is the active component of an intravenous anesthetic formulation used for induction and maintenance of general anesthesia. The formulation was approved under the brand name Diprivan. Numerous generic versions have since been released. Intravenous administration is used to induce unconsciousness, after which anesthesia may be maintained using a combination of medications. It is manufactured as part of a sterile injectable emulsion formulation using soybean oil and lecithin, giving it a white milky coloration.

Thymol (also known as 2-isopropyl-5-methylphenol, IPMP), , is a monoterpenoid, phenol derivative of p-cymene, isomeric with carvacrol. It occurs naturally in oil of thyme and is extracted from Thymus vulgaris (common thyme), ajwain, and various other plants, as a white crystalline substance with a pleasant aromatic odor.

Carvacrol, or cymophenol, C6H3(CH3)(OH)C3H7, is a monoterpenoid phenol. It has a characteristic pungent, warm odor of oregano.

Creosol is a chemical compound with the molecular formula C8H10O2. It is one of the components of creosote. Compared with phenol, creosol is a less toxic disinfectant.

Nonylphenols are a family of closely related organic compounds composed of phenol bearing a 9 carbon-tail. Nonylphenols can come in numerous structures, all of which may be considered alkylphenols. They are used in manufacturing antioxidants, lubricating oil additives, laundry and dish detergents, emulsifiers, and solubilizers. They are used extensively in epoxy formulation in North America but its use has been phased out in Europe. These compounds are also precursors to the commercially important non-ionic surfactants alkylphenol ethoxylates and nonylphenol ethoxylates, which are used in dete

'''tert-Butylhydroquinone (TBHQ, tertiary butylhydroquinone, tBHQ') is a synthetic aromatic organic compound which is a type of phenol. It is a derivative of hydroquinone, substituted with a tert''-butyl group.

'''ortho-Cresol (IUPAC name: 2-methylphenol, also known as 2-hydroxytoluene or ortho-toluenol') is an organic compound with the formula CH3C6H4(OH). It is a colourless solid that is widely used intermediate in the production of other chemicals. It is a derivative of phenol and is an isomer of p-cresol and m''-cresol.

A calixarene is a macrocycle or cyclic oligomer based on a methylene-linked phenols. With hydrophobic cavities that can hold smaller molecules or ions, calixarenes belong to the class of cavitands known in host–guest chemistry.

Ethylphenol (4-EP) is an organic compound with the formula C2H5C6H4OH. It is one of three isomeric ethylphenols. A white solid, it occurs as an impurity in xylenols and as such is used in the production of some commercial phenolic resins. It is also a precursor to 4-vinylphenol.

4-Ethylguaiacol, often abbreviated to 4-EG, is a phenolic compound with the molecular formula C9H12O2 that's a key aromatic component in various products, from food and beverages to cosmetics and pharmaceuticals. It can be produced in wine and beer by Brettanomyces. It is also frequently present in bio-oil produced by pyrolysis of lignocellulosic biomass.

Amylmetacresol (AMC) is an antiseptic used to treat infections of the mouth and throat. It is used as an active pharmaceutical ingredient in Strepsils, Cēpacol, Gorpils, Cofsils and Lorsept throat lozenges, typically in combination with dichlorobenzyl alcohol, another antiseptic.

thumb|right|Chemical structure of the alkylphenol nonylphenol Alkylphenols are a family of organic compounds obtained by the alkylation of phenols. The term is usually reserved for commercially important propylphenol, butylphenol, amylphenol, heptylphenol, octylphenol, nonylphenol, dodecylphenol and related "long chain alkylphenols" (LCAPs). Methylphenols and ethylphenols are also alkylphenols, but they are more commonly referred to by their specific names, cresols and xylenols. Some members of this group of compounds have proven controversial.

Xylenols are organic compounds with the formula (CH3)2C6H3OH. They are volatile colorless solids or oily liquids. They are derivatives of phenol with two methyl groups at various positions relative to the hydroxyl group. Six isomers exist, of which 2,6-xylenol with both methyl groups in an ortho position with respect to the hydroxyl group is the most important. The name xylenol is a portmanteau of the words xylene and phenol.

2,6-Xylenol is a chemical compound which is one of the six isomers of xylenol. It is also commonly known as 2,6-dimethylphenol (DMP). It is a colorless solid.

'4-tert-Butylcatechol' (TBC) is an organic chemical compound which is a derivative of catechol. TBC is available in the form of a solid crystal flake and 85% solution in methanol or water.

'2,6-Di-tert-butylphenol' is an organic compound with the structural formula 2,6-((CH3)3C)2C6H3OH. This colorless solid alkylated phenol and its derivatives are used industrially as UV stabilizers and antioxidants for hydrocarbon-based products ranging from petrochemicals to plastics. Illustrative of its usefulness, it prevents gumming in aviation fuels.

Mesitol (2,4,6-trimethylphenol) is an organic compound with the formula (CH3)3C6H2OH. It is one of several isomers of trimethylphenol. The name and structure of mesitol derives from the combination of mesitylene and phenol.

3,4-Xylenol is a chemical compound which is one of the six isomers of xylenol.

1-Nonyl-4-phenol is an organic compound consisting of an n-nonyl group attached to the 4-position of phenol. The related nonylphenols with branched nonyl groups are commercially important detergents. It is used with mixed-metals stabilizers for heat stabilization of plastic and is a starting material for producing phenol resins. 1-Nonyl-4-phenol is insoluble in water, but soluble in organic compounds like benzene and heptane.

'2,4-Dimethyl-6-tert-butylphenol' is the organic compound with the formula Me2(tert-Bu)C6H2OH (Me = methyl, tert-Bu = tertiary butyl). It is a colorless oil that is classified as an alkylated phenol.

2,3,6-Trimethylphenol is an organic compound with the formula (CH3)3C6H2OH. As a precursor to vitamin E, it is the most widely used of the several isomers of trimethylphenol.

2-Ethyl-4,5-dimethylphenol is a phenol found in the essential oil of rosemary (Rosmarinus officinalis). It is also found in female elephant urine samples.

3-Ethylphenol is an organic compound with the formula C2H5C6H4OH. It is one of three isomeric ethylphenols. A colorless liquid, it occurs as an impurity in xylenols and as such is used in the production of commercial phenolic resins.
