  2. 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 ).

  3. Methanesulfonyl azide - Wikipedia

    en.wikipedia.org/wiki/Methanesulfonyl_azide

    Methanesulfonyl azide melts at 18 °C and decomposes from 120 °C. [1] Like many other azides, it is explosive. [3] At low temperature, methanesulfonyl azide crystallizes in the triclinic crystal system in the space group P1 with the lattice parameters a = 5.6240 Å; b = 5.9498 Å, c = 7.6329 Å, α = 72.216°, β = 70.897°, and γ = 88.601°, and two molecules per unit cell.

  4. Sulfonic acid - Wikipedia

    en.wikipedia.org/wiki/Sulfonic_acid

    Sulfonic acids are strong acids. They are commonly cited as being around a million times stronger than the corresponding carboxylic acid. For example, p-Toluenesulfonic acid and methanesulfonic acid have pK a values of −2.8 and −1.9, respectively, while those of benzoic acid and acetic acid are 4.20 and 4.76, respectively

  5. Methanedisulfonic acid - Wikipedia

    en.wikipedia.org/wiki/Methanedisulfonic_acid

    Methanedisulfonic acid is the organosulfur compound with the formula CH 2 (SO 3 H) 2. It is the disulfonic acid of methane. It is prepared by treatment of methanesulfonic acid with oleum. Its acid strength (pK a) is comparable to that of sulfuric acid. [3]

  6. Mesylate - Wikipedia

    en.wikipedia.org/wiki/Mesylate

    In organosulfur chemistry, a mesylate is any salt or ester of methanesulfonic acid (CH 3 SO 3 H). In salts, the mesylate is present as the CH 3 SO − 3 anion . When modifying the international nonproprietary name of a pharmaceutical substance containing the group or anion, the spelling used is sometimes mesilate (as in imatinib mesilate , the ...

  8. Sulfenic acid - Wikipedia

    en.wikipedia.org/wiki/Sulfenic_acid

    In chemistry, a sulfenic acid is an organosulfur compound and oxoacid with the general formula R−S−OH. It is the first member of the family of organosulfur oxoacids, which also include sulfinic acids (R−S(=O)OH) and sulfonic acids (R−S(=O) 2 OH), respectively. The base member of the sulfenic acid series with R = H is hydrogen thioperoxide.
