Uses

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.

Uses

Metanilic 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. It undergoes microbial desulfonation to 3-aminophenol by Pseudomonas sp. strain S-313. It can be used to produce CN3O6(1-)*Cs(1+) and dicesium salt of N-nitrometanilic acid at temperature of 25°C.

Definition

ChEBI: 3-aminobenzenesulfonic acid is an aminobenzenesulfonic acid. It is a conjugate acid of a 3-aminobenzenesulfonate.

Flammability and Explosibility

Nonflammable

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.]
