    [1] [5] [6] [7]: 104 Some phenols are germicidal and are used in formulating disinfectants. Phenol – the simplest of the phenols Chemical structure of salicylic acid, the active metabolite of aspirin Chemical structure of aloe emodin, a diphenol Quercetin, a typical flavonoid, is a polyphenol Tannic acid, a typical polyphenol of indeterminate ...

  3. Ferric chloride test - Wikipedia

    en.wikipedia.org/wiki/Ferric_chloride_test

    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]

  4. Phenols - Wikipedia

    en.wikipedia.org/wiki/Phenols

    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 molecule. Phenol – the simplest of the phenols Chemical structure of salicylic acid, the active metabolite of aspirin. Phenols are both synthesized industrially and produced by plants and ...

  5. Phenol extraction - Wikipedia

    en.wikipedia.org/wiki/Phenol_extraction

    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.

  7. Phenol coefficient - Wikipedia

    en.wikipedia.org/wiki/Phenol_coefficient

    To calculate phenol coefficient, the concentration of phenol at which the compound kills the test organism in 10 minutes, but not in 5 minutes, is divided by the concentration of the test compound that kills the organism under the same conditions (or, probably more common, dividing the dilution factor at which the tested substance shows ...

  8. Colorimetric analysis - Wikipedia

    en.wikipedia.org/wiki/Colorimetric_analysis

    Colorimetric analysis is a method of determining the concentration of a chemical element or chemical compound in a solution with the aid of a color reagent. It is applicable to both organic compounds and inorganic compounds and may be used with or without an enzymatic stage.

  9. Trizol - Wikipedia

    en.wikipedia.org/wiki/Trizol

    TRIzol reagent contains guanidinium thiocyanate and phenol.. TRIzol is a widely used [1] chemical solution used in the extraction of DNA, RNA, and proteins from cells. The solution was initially used and published by Piotr ChomczyƄski and Nicoletta Sacchi in 1987.
