Description and Uses
2,3, 4-trihydroxybenzaldehyde is an essential intermediate of the antiparkinson drug benserazide, which is a peripheral dopa decarboxylase inhibitor, usually benserazide: the L-dopa is prepared into a compound preparation at a ratio of 1:4, and has a remarkable effect of treating the Parkinson's disease.
2,3,4-Trihydroxybenzaldehyde has been used in the preparation of 1,5-dimethyl-2-phenyl-4-[(1E)-(2,3,4-trihydroxybenzylidene)amino]-1H-pyrazol-3(2H)-one.
