Para-Toluenesulfonic acid (PTSA, pTSA, or pTsOH) or tosylic acid (TsOH) is an organic compound with the formula CH 3 C 6 H 4 SO 3 H. It is a white extremely hygroscopic solid that is soluble in water, alcohols, and other polar organic solvents. [6] The CH 3 C 6 H 4 SO 2 group is known as the tosyl group and is often abbreviated as Ts or Tos.

Toluene-4-sulfonic acid is an arenesulfonic acid that is benzenesulfonic acid in which the hydrogen at position 4 is replaced by a methyl group. It is a member of toluenes and an arenesulfonic acid. It is a conjugate acid of a toluene-4-sulfonate. See also: Abexinostat (part of); Benzenesulfonic acid, 2 (or 4)-methyl- (annotation moved to).

p-Toluenesulfonic acid (PTSA), or tosylic acid (TsOH), is a corrosive, toxic, solid, strong organic acid. In monohydrate form, its formula is TsOH·H2O. Available in various quantities, PTSA is used as an organic-soluble acid catalyst in organic synthesis.

p-TsOH is one of the most commonly used organic acid catalysts. p -TsOH is a strong organic acid. Unlike most strong acids, p -TsOH exists as a convenient to handle solid.

p-Toluenesulfonic acid (PTSA) is an organic compound with the formula CH 3 C 6 H 4 SO 3 H. TsOH, as it is abbreviated, is a white solid that is soluble in water, alcohols, and other polar organic solvents. Most often, TsOH refers to the mono hydrate, TsOH. H 2 O. TsOH is a strong organic acid, about a million times stronger than benzoic acid.

Jul 24, 2024 · p-Toluenesulfonic acid (PTSA or pTsOH) or tosylic acid (TsOH) is an organic compound with the formula CH 3 C 6 H 4 SO 3 H. It is a white solid that is soluble in water, alcohols, and other polar organic solvents.

We document here the use of polymer-supported p-toluenesulfonic acid as a highly effective, robust, economical and eco-friendly isocyanide scavenger. The herein described strategy circumvent the intense and repulsive odor of volatile isocyanides, enabling simplified and odorless workup and purifications.
