| | P-TOLUENESULFINIC ACID Usage And Synthesis |
| 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. |
