General description
Antimicrobial activity of carbohydrazone derived from 2,3,4-trihydroxybenzaldehyde against bacteria and fungi has been investigated. 2,3,4-trihydroxybenzaldehyde forms Schiff bases via [1+1] condensation with anthranilic acid.
Application
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.
