Application

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

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.

2,4-Dihydroxybenzaldehyde is a potential building block for bioactive compounds, specialty chemicals and dyes.
