p-formylbenzenesulphonic acid

Uses

4-Formylbenzenesulfonic Acid is used in preparation method for 3-Phenyl-L-serine derivatives.

Definition

ChEBI: 4-formylbenzenesulfonic acid is an arenesulfonic acid. It is a conjugate acid of a 4-formylbenzenesulfonate.

Production Methods

4-Formylbenzenesulfonic acid (p-formylbenzenesulphonic acid) is produced by oxidation of p- toluenesulfonic acid with manganese dioxide in 25% oleum or by oxidation of p-toluenesulfonyl chloridein glacial acetic acid – acetic anhydride with chromium trioxide and concentrated sulfu- ric acid at 0 ℃ and hydrolysis of the sulfonyl chloride of the aldehyde-hydrate diacetate with dilute hydrochloric acid.
