2,4-Dihydroxybenzaldehyde Chemical Properties, Uses, Production

Chemical Properties

2,4-Dihydroxybenzaldehyde is cream to light brown solid

Uses

2,4-Dihydroxybenzaldehyde is usually used in two-step synthesis of ethyl 3,5-dibromo-2,4-dihydroxycinnamate.

Description

2,4-Dihydroxybenzaldehyde is a resorcinol (R144700) derivative with potent antioxidative and antibacterial activity.

Reactions

2,4-Dihydroxybenzaldehyde was used in two-step synthesis of ethyl 3,5-dibromo-2,4-dihydroxycinnamate.

Definition

ChEBI: 2,4-dihydroxybenzaldehyde is a dihydroxybenzaldehyde that is resorcinol which has been substituted by a formyl group para to one of the hydroxy groups.

General Description

2,4-Dihydroxybenzaldehyde undergoes regioselective mono-benzylation reaction under extremely mild basic conditions. It undergoes condensation reaction with isonicotinic acid hydrazide in methanol to yield 2,4-dihydroxybenzaldehyde isonicotinoyl hydrazone, a new fluorescent reagent.

Synthesis

1,3-Dihydroxybenzene and cyclodextrin are dissolved in an aqueous solution of NaOH or KOH, and chloroform is added thereto and reacted at 50-80 deg.C to give the aimed compound 2,4-Dihydroxybenzaldehyde.
