Product Details

Description

Furan-2-carboxylic acid is a natural miscellaneou found in the herbs of Hexagonia speciosa. Furan-2-carboxylic acid is most widely found in food products as a preservative and a flavoring agent. For its anti-bacteria effect, 2-Furoic acid can inhibit the proliferation of some slow-growing or difficult-to-culture bacteria on the plates.

Definition

ChEBI: 2-furoic acid is a furoic acid having the carboxylic acid group located at position 2. It has a role as an inhibitor, a human xenobiotic metabolite, a Saccharomyces cerevisiae metabolite, a plant metabolite and a bacterial xenobiotic metabolite. It is a conjugate acid of a 2-furoate.

Preparation

2-furoic acid can be synthesized by the oxidation of furfural. The reaction was carried out at 45°C with vigorous stirring. The reactant is filtered to recover the catalyst copper oxide, the filtrate is acidified with 50% sulfuric acid to pH 3-2.5, suction filtered, washed with water, and dried to obtain 2-furoic acid.

Purification Methods

Crystallise the acid from hot water (charcoal), dry it at 120o for 2hours, then recrystallise it from CHCl3, and again dry it at 120o for 2hours. For use as a standard in volumetric analysis, good quality commercial acid should be crystallised from CHCl3 and dried as above or sublimed at 130-140o/50-60mm or less.
