  2. Methylsulfonylmethane - Wikipedia

    en.wikipedia.org/wiki/Methylsulfonylmethane

    Dimethyl sulfone (DMSO 2) is an organosulfur compound with the formula (CH 3) 2 SO 2. It is also known by several other names including methyl sulfone and (especially in alternative medicine) methylsulfonylmethane (MSM). [4] This colorless solid features the sulfonyl functional group and is the simplest of the sulfones. It is relatively inert ...

  3. Methanesulfonyl fluoride - Wikipedia

    en.wikipedia.org/wiki/Methanesulfonyl_fluoride

    [6] [3] MSF, which is a liquid at room temperature, has a vapor pressure of 19.2 mmHg, slightly more volatile than water which has a vapor pressure of 18.8 mmHg at 21 °C. This vapor has an LCt 50 (lethal concentration, 50% death rate in a given time) in rats of between 4 and 5 parts per million (ppm) during one hour of exposure or between 1 ...

  4. Sulfonyl halide - Wikipedia

    en.wikipedia.org/wiki/Sulfonyl_halide

    The sulfonyl chlorides and fluorides are of dominant importance in this series. [1] [2] Sulfonyl halides have tetrahedral sulfur centres attached to two oxygen atoms, an organic radical, and a halide. In a representative example, methanesulfonyl chloride, the S=O, S−C, and S−Cl bond distances are respectively 142.4, 176.3, and 204.6 pm. [3]

  5. PMSF - Wikipedia

    en.wikipedia.org/wiki/PMSF

    Alternative sulfonyl fluoride reagents like p-APMSF and HDSF, have altered access to native folded protein structures, and may react with serine enzymes that PMSF cannot efficiently react with. This altered selectivity between sulfonyl fluoride reagents has been used to classify and isolate particular types of serine enzymes.

  6. Triflidic acid - Wikipedia

    en.wikipedia.org/wiki/Triflidic_acid

    Triflidic acid (IUPAC name: tris[(trifluoromethyl)sulfonyl]methane, abbreviated formula: Tf 3 CH) is an organic superacid. It is one of the strongest known carbon acids and is among the strongest Brønsted acids in general, with an acidity exceeded only by the carborane acids .

  7. Methanesulfonic acid - Wikipedia

    en.wikipedia.org/wiki/Methanesulfonic_acid

    Methanesulfonic acid (MsOH, MSA) or methanesulphonic acid (in British English) is an organosulfuric, colorless liquid with the molecular formula CH 3 SO 3 H and structure H 3 C−S(=O) 2 −OH. It is the simplest of the alkylsulfonic acids ( R−S(=O) 2 −OH ).

  8. Sulfonamide - Wikipedia

    en.wikipedia.org/wiki/Sulfonamide

    The general formula is R−SO 2 NR'R" or R−S(=O) 2 −NR'R", where each R is some organic group; for example, "methanesulfonamide" (where R = methane, R' = R" = hydrogen) is CH 3 SO 2 NH 2. Any sulfonamide can be considered as derived from a sulfonic acid by replacing a hydroxyl group ( −OH ) with an amine group.

  9. Triflate - Wikipedia

    en.wikipedia.org/wiki/Triflate

    In organic chemistry, triflate (systematic name: trifluoromethanesulfonate), is a functional group with the formula R−OSO 2 CF 3 and structure R−O−S(=O) 2 −CF 3. The triflate group is often represented by −OTf, as opposed to −Tf, which is the triflyl group, R−SO 2 CF 3. For example, n-butyl triflate can be written as CH 3 CH 2 CH ...
