Chemical properties
BEIGE TO YELLOW-ORANGE CRYSTALLINE POWDER
The Uses of 4-NITROBENZENESULFONIC ACID
4-Nitrobenzenesulfonic acid is used in the preparation of diaryl compounds as antiviral agents.
The Uses of 4-NITROBENZENESULFONIC ACID
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.
Production Methods
4-Nitrobenzenesulfonic acid is produced by hydrolysis of 4-nitrobenzenesulfonyl chloride.
