2,5-Dihydroxybenzaldehyde Chemical Properties, Uses, Production

Description

2,5-Dihydroxybenzaldehyde is a building block. It has been used in the synthesis of 2,4-dimethylbenzoylhydrazones with antileishmanial and antioxidant activity.

Chemical Properties

yellow to khaki-green crystalline powder

Uses

2,5-Dihydroxybenzaldehyde (cas# 1194-98-5) is a compound useful in organic synthesis.

Application

2,5-Dihydroxybenzaldehyde is a is a natural phenol found in the heartwoods of Pseudolarix amabilis, it is a tyrosine kinase inhibitor. 2,5-Dihydroxybenzaldehyde has antimicrobial activity and is mostly used in experimental studies for the preparation of Schiff base derivatives and bioanodes for glucose fuel cells.

Preparation

Add 80 mmol of dry paraformaldehyde to a mixture of 12 mmol of the phenol derivative and 2.5 mmol of MgO nanocrystalline (0.1 g). Expose the resulting mixture under microwave irradiation with a power of 650 W. Monitor the progress of the reaction by thin layer chromatography (TLC) developed by n-hexane : ethyl acetate (8 : 2). Add 100 mL of sulfuric acid (15% w/w) to the reaction mixture and heated at 50 °C for 15 min. Cool the reaction mixture to room temperature. Extract the product by dichloromethane (2 x 50 mL). Dry the organic layer over anhydrous magnesium sulphate. Evaporate the solution resulting from filtration to obtain the crude product. Purify the other product by column chromatography using n-hexane : ethyl acetate (95 : 5 to 70 : 30).
