150-13-0 Usage

Chemical Properties

White to off white crystalline powder

Uses

gastric acid secretion inhibitor

Definition

ChEBI: An aminobenzoic acid in which the amino group is para to the carboxy group.

General Description

Colorless crystals that discolor on exposure to light and air.

Reactivity Profile

4-Aminobenzoic acid is incompatible with ferric salts and oxidizing agents.

Uses

Widely distributed in nature as a B complex factor. Baker’s yeast contains 5 to 6 ppm, brewer’s yeast from 10 to 100 ppm. Occurs free and in ester form.

Purification Methods

Purify p-aminobenzoic acid by dissolving it in 4-5% aqueous HCl at 50-60o, decolorising with charcoal and carefully precipitating it with 30% Na2CO3 to pH 3.5-4 in the presence of ascorbic acid. It can be recrystallised from water, EtOH or EtOH/water mixtures. [Beilstein 14 IV 1126.]
