Metanilic acid Chemical Properties,Uses,Production
Chemical Properties
white powder
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.
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.
Hazard
See aniline.
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.]
