  2. Methylsulfonylmethane - Wikipedia

    en.wikipedia.org/wiki/Methylsulfonylmethane

    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 chemically and is able to resist decomposition at elevated temperatures.

  3. Methanesulfonic acid - Wikipedia

    en.wikipedia.org/wiki/Methanesulfonic_acid

    German chemist Hermann Kolbe discovered MSA between 1842 and 1845 and originally termed it methyl hyposulphuric acid. [ 4 ] [ 5 ] [ 6 ] The discovery stemmed from earlier work by Berzelius and Marcet in 1813, who treated carbon disulfide with moist chlorine and produced a compound they named "sulphite of chloride of carbon".

  4. Methanesulfonyl chloride - Wikipedia

    en.wikipedia.org/wiki/Methanesulfonyl_chloride

    Methanesulfonyl chloride is mainly used to give methanesulfonates by its reaction with alcohols in the presence of a non-nucleophilic base. [8] In contrast to the formation of toluenesulfonates from alcohols and p-toluenesulfonyl chloride in the presence of pyridine, the formation of methanesulfonates is believed to proceed via a mechanism wherein methanesulfonyl chloride first undergoes an ...

    en.wikipedia.org/wiki/Methyl_methanesulfonate

    Methyl methanesulfonate (MMS), also known as methyl mesylate, is an alkylating agent and a carcinogen. It is also a suspected reproductive toxicant, and may also be a ...

  6. Sulfonic acid - Wikipedia

    en.wikipedia.org/wiki/Sulfonic_acid

    General structure of a sulfonic acid with the functional group indicated in blue. In organic chemistry, sulfonic acid (or sulphonic acid) refers to a member of the class of organosulfur compounds with the general formula R−S(=O) 2 −OH, where R is an organic alkyl or aryl group and the S(=O) 2 (OH) group a sulfonyl hydroxide. [1]

  7. 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.

  8. Methanesulfonic anhydride - Wikipedia

    en.wikipedia.org/wiki/Methanesulfonic_anhydride

    Ms 2 O can be purified by distillation under vacuum (distillation of a solid) or by recrystallization from Methyl tert-butyl ether/toluene.

  9. Sulfonyl group - Wikipedia

    en.wikipedia.org/wiki/Sulfonyl_group

    A sulfone. It consists of a sulfonyl group bonded with two organic substituents. In organosulfur chemistry, a sulfonyl group is either a functional group found primarily in sulfones, or a substituent obtained from a sulfonic acid by the removal of the hydroxyl group, similarly to acyl groups. [1]: 1470–1476
