121-57-3 Usage

Fire Hazard

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

General Description

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

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.]

Reactivity Profile

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

Uses

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

Air & Water Reactions

Insoluble in water.

Chemical Properties

greyish-white crystals or powder

Definition

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