  2. Phenol red - Wikipedia

    en.wikipedia.org/wiki/Phenol_red

    Phenol red exists as a red crystal that is stable in air. Its solubility is 0.77 grams per liter (g/L) in water and 2.9 g/L in ethanol. [1] It is a weak acid with pK a = 8.00 at 20 °C (68 °F). A solution of phenol red is used as a pH indicator, often in cell culture.

  3. Safety data sheet - Wikipedia

    en.wikipedia.org/wiki/Safety_data_sheet

    An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.

  4. Phenol - Wikipedia

    en.wikipedia.org/wiki/Phenol

    Phenol is an organic compound appreciably soluble in water, with about 84.2 g dissolving in 1000 ml (0.895 M).Homogeneous mixtures of phenol and water at phenol to water mass ratios of ~2.6 and higher are possible.

  5. Chlorophenol - Wikipedia

    en.wikipedia.org/wiki/Chlorophenol

    A chlorophenol is any organochloride of phenol that contains one or more covalently bonded chlorine atoms. There are five basic types of chlorophenols (mono- to pentachlorophenol) and 19 different chlorophenols in total when positional isomerism is taken into account. Chlorophenols are produced by electrophilic halogenation of phenol with ...

  6. 2,4,6-Trichlorophenol - Wikipedia

    en.wikipedia.org/wiki/2,4,6-Trichlorophenol

    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.

  7. Chlorophenol red - Wikipedia

    en.wikipedia.org/wiki/Chlorophenol_red

    Chlorophenol red is an indicator dye that changes color from yellow to violet in the pH range 5.4 to 6.8. [2] The pH of a substance is determined by taking the negative logarithm of the Hydronium ion concentration and the indictor changes color due to the dissociation of H + ions. [ 3 ]

  8. Cresol - Wikipedia

    en.wikipedia.org/wiki/Cresol

    Like other types of phenols, they are slowly oxidized by exposure to air, and the resulting impurities often give the samples a yellow to brownish red tint. Cresols have an odor characteristic to that of other simple phenols, reminiscent to some of a "coal tar" smell. The name "cresol" is an adduct of phenol and their traditional source, creosote.

  9. Cresol Red - Wikipedia

    en.wikipedia.org/wiki/Cresol_Red

    Cresol red (full name: o-cresolsulfonephthalein) [1] is a triarylmethane dye frequently used for monitoring the pH in aquaria. Cresol red (pH indicator) below pH 7.2:
