Metanilic acid Chemical Properties,Uses,Production

Chemical Properties

white powder


3-Aminobenzenesulfonic acid was used in the synthesis of cytocompatible sulfonated polyanilines. It was used in fabrication of novel glucose biosensor having large active surface area and excellent conductivity.

General Description

White powder. Small colorless needles; toxic.

Air & Water Reactions

Water insoluble [Hawley].

Reactivity Profile

Metanilic acid is an amino acid. Reacts weakly with both acids and bases.

Fire Hazard

Flash point data for Metanilic acid are not available, however Metanilic acid is probably combustible.

Purification Methods

Crystallise the acid from water (as the hydrate), under CO2 in a semi-darkened room. The solution is photosensitive. Dry it over 90% H2SO4 in a vacuum desiccator. [Beilstein 14 H 688, 14 IV 2640.]
