Chemical Properties

LIGHT BROWN FINE CRYSTALLINE POWDER

Definition

ChEBI: An aminobenzenesulfonic acid carrying an amino group at position 2.

General Description

Light brown powder.

Air & Water Reactions

Soluble in water.

Reactivity Profile

Aniline-2-sulfonic acid is an amino acid. Reacts weakly with both acids and bases.

Fire Hazard

Flash point data for Aniline-2-sulfonic acid are not available, however Aniline-2-sulfonic acid is probably combustible.

Purification Methods

Crystallise orthanilic acis from aqueous solution, containing 20mL of conc HCl per L, then crystallise it from distilled water, and dry it in a vacuum desiccator over Sicapent (m 315o). When an aqueous solution is chilled below 13.5o, the hydrated form of the acid is obtained. It is used for the determination of nitrite and nitrate. The S-benzylisothiuronium salt has m 137o (from H2O). [Wertheim Org Synth Coll Vol II 471 1943, Beilstein 14 H 681, 14 I 714, 14 II 429, 14 III 1896, 14 IV 2638.]
