4-Hydroxy-3-nitrobenzaldehyde was used in the synthesis of:
- 4-hydroxy-3-nitrocinnamic acid
- solvated benzohydrazone derivatives: N′-(4-hydroxy-3-nitrobenzylidene)-3-methylbenzohydrazide-methanol-water
4-Hydroxy-3-nitrobenzaldehyde is an Intermediate used in synthesis of novel amodiaquine analogs as potential antimalarial and antifilarial compounds.
4-Hydroxy-3-nitrobenzaldehyde reacts with 3-bromo-benzohydrazide in methanol to yield (E)-3-bromo-N′-(4-hydroxy-3-nitrobenzylidene)benzohydrazide.
