2,4-Dihydroxybenzaldehyde Usage And Synthesis

Chemical Properties	2,4-Dihydroxybenzaldehyde is cream to light brown solid
Uses	2,4-Dihydroxybenzaldehyde is a resorcinol (R144700) derivative with potent antioxidative and antibacterial activity.
Uses	2,4-Dihydroxybenzaldehyde is usually used in two-step synthesis of ethyl 3,5-dibromo-2,4-dihydroxycinnamate.
Uses	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.
