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. |
