Sulfanilic acid Chemical Properties,Uses,Production

Chemical Properties

greyish-white crystals or powder

Uses

A toxic metabolite of Tartrazine (T007700). Used as Ehrlich’s reagent, for detecting of nitrites. Antibacterial.

Definition

ChEBI: An aminobenzenesulfonic acid that is aniline sulfonated at the para-position.

General Description

White powder with faint purple tinge. Grayish-white flat crystals. Becomes anhydrous at around 212°F. Low toxicity (used medicinally).

Air & Water Reactions

Insoluble in water.

Reactivity Profile

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

Fire Hazard

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

Purification Methods

Crystallise the acid (as dihydrate) from boiling water. Dry it at 105o for 2-3hours, then over 90% H2SO4 in a vacuum desiccator. The S-benzylisothiuronium salt has m 187o (from aqueous EtOH). [Beilstein 14 IV 2655.]
