4-Aminobenzoic acid Chemical Properties,Uses,Production

Description

4-Aminobenzoic acid (also known as para-aminobenzoic acid or PABA because the number 4 carbon in the benzene ring is also known as the para position) is an organic compound with the formula H2NC6H4CO2H. PABA is a white solid, although commercial samples can appear gray. It is slightly soluble in water. It consists of a benzene ring substituted with amino and a carboxyl groups. The compound occurs naturally. The potassium salt is used as a drug against fibrotic skin disorders, such as Peyronie's disease, under the trade name Potaba. PABA is also occasionally used in pill form by sufferers of irritable bowel syndrome to treat its associated gastrointestinal symptoms, and in nutritional epidemiological studies to assess the completeness of 24-hour urine collection for the determination of urinary sodium, potassium, or nitrogen levels.

Chemical Properties

White to off white crystalline powder

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.

Uses

gastric acid secretion inhibitor

Uses

octyl dimethyl PABA (padimate-O; p-aminobenzoic acid) is an FDA-approved sunscreen chemical whose InCI name is now ethylhexyl dimethyl PABA.

Uses

PABA is a sunscreen chemical with an approved usage level of 5 to 15 percent. It is found to be irritating to sensitive skin, has the potential to cause sensitization, and is considered too water soluble. once extremely popular, this ingredient has practically disappeared from sunscreen formulations. PABA is a yellowish or colorless acid found in vitamin B complex.

Definition

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

brand name

RVPaba Lipstick (ICN).

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.

Hazard

Questionable carcinogen.

Safety Profile

Moderately toxic by ingestion and intravenous routes. Ingesting large doses can cause nausea, vomiting, skin rash, methemoglobinemia, and possibly toxic hepatitis. Experimental reproductive effects. Mutation data reported. Questionable carcinogen. Combustible. When heated to decomposition it emits toxic fumes of NO,. A topical sunscreen.

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.]
