In female elephants, the two compounds 3-ethyl phenol and 2-ethyl 4,5 dimethylphenol have been detected in urine samples. [70] Temporal glands secretion examination showed the presence of phenol, m-cresol and p-cresol (4-methyl phenol) during musth in male elephants. [71] [72] [73] p-Cresol and o-cresol are also components of the human sweat.
The best-selling drug in the U.S., Acetaminophen, also known as Paracetamol, is a phenol. There are various classification schemes. [15]: 2 A commonly used scheme is based on the number of carbons and was devised by Jeffrey Harborne and Simmonds in 1964 and published in 1980: [15]: 2 [16]
Phenol (C 6 H 5 OH) is a water-soluble compound consisting of a phenyl group (-C 6 H 5) bonded to a hydroxyl group (-OH). Phenol extraction is a widely used technique for purifying nucleic acid samples from cell lysates. [1] To obtain nucleic acids, the cell must be lysed, and the nucleic acids separated from other cell components.
The ferric chloride test is used to determine the presence of phenols in a given sample or compound (for instance natural phenols in a plant extract). Enols, hydroxamic acids, oximes, and sulfinic acids give positive results as well. [1]
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 ).
Alkali metal phenolates, such as sodium phenolate hydrolyze in aqueous solution to form basic solutions. [2] At pH = 10, phenol and phenolate are in approximately 1:1 proportions. The phenoxide anion (aka phenolate ) is a strong nucleophile with a comparable to the one of carbanions or tertiary amines. [ 3 ]
The solution was initially used and published by Piotr Chomczyński and Nicoletta Sacchi in 1987. [ 2 ] TRIzol is the brand name of guanidinium thiocyanate from the Ambion part of Life Technologies , [ 3 ] and Tri-Reagent is the brand name from MRC, [ 4 ] which was founded by Chomczynski.
2,4,6-Trichlorophenol, also known as TCP, phenaclor, Dowicide 2S, Dowcide 2S, omal, is a chlorinated phenol that has been used as a fungicide, herbicide, insecticide, antiseptic, [3] defoliant, and glue preservative. [4] It is a clear to yellowish crystalline solid with a strong, phenolic odor.
