P-TOLUENESULFINIC ACID Chemical Properties,Usage,Production

  • Uses p-toluenesulfinic acid is used in preparation of alkyl, vinyl, and allyl sulfones; starting material for the preparation of chiral sulfoxides; mild acid catalyst.
  • Synthesis Reference(s) Chemical and Pharmaceutical Bulletin, 35, p. 1770, 1987 DOI: 10.1248/cpb.35.1770
  • Synthesis p-toluenesulfinic acid is prepared by isolation of the free acid via acidification of an aqueous solution of the sodium salt has been described; partial conversion to p-Toluenesulfonic Acid frequently accompanies drying of the free acid.
  • storage It should be stored in a cool, dry place away from strong oxidizing agents.
