2,3-Dihydroxybenzaldehyde Chemical Properties,Usage,Production
Chemical Properties
light yellow to beige-greenish cryst. powder
Uses
2,3-disubstituted benzaldehyde.
Uses
2,3-Dihydroxybenzaldehyde was used in the synthesis of copper(II) complexes of Schiff bases. It was also used in the synthesis of 2-ethoxy-3-hydroxy-4-nitrobenzoic acid.
Definition
ChEBI: 2,3-dihydroxybenzaldehyde is a dihydroxybenzaldehyde.
General Description
Electrochemical oxidation of 2,3-dihydroxybenzaldehyde in methanol at various pH has been studied using cyclic voltammetry and controlled-potential coulometry.
Synthesis
148-53-8
24677-78-9
The general procedure for the synthesis of 2,3-dihydroxybenzaldehyde from o-vanillin was as follows: acetonitrile (40 ml) was added to a 100 ml aubergine flask, followed by sequential addition of aluminum trichloride (0.752 g, 5.64 mmol, 1.1 equiv), sodium iodide (2.305 g, 15.38 mmol, 3.0 equiv) and o-vanillin (0.780 g, 5.13 mmol). The reaction mixture was heated to 80 °C and the reaction was stirred for 18 hours. After completion of the reaction, the heating was stopped and cooled to room temperature. The reaction solution was acidified with 2 mol/L dilute hydrochloric acid (10 ml) and subsequently extracted with ethyl acetate (50 ml x 3). The organic phases were combined and washed sequentially with saturated aqueous sodium thiosulfate (10 ml) and saturated brine (10 ml). The organic phase was dried with anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. Purification by column chromatography afforded 2,3-dihydroxybenzaldehyde (0.620 g, yellow solid, 87% yield).
Purification Methods
Crystallise the aldehyde from water. [Beilstein 8 III 1979.]
