4-NITROBENZENESULFONIC ACID Chemical Properties,Uses,Production

Chemical Properties

BEIGE TO YELLOW-ORANGE CRYSTALLINE POWDER

Uses

4-Nitrobenzenesulfonic acid is less important than the ortho and meta isomers because sulfanilic acid and its derivatives are readily available from aniline and acetanilide.

Uses

4-Nitrobenzenesulfonic acid is used in the preparation of diaryl compounds as antiviral agents.

Production Methods

4-Nitrobenzenesulfonic acid is produced by hydrolysis of 4-nitrobenzenesulfonyl chloride.
