4-Nitrocinnamaldehyde
4-Nitrocinnamaldehyde is a diazonium salt that is used as an efficient method for the synthesis of nitro compounds. Nitro compounds are used in the production of explosives, insecticides, and herbicides. 4-Nitrocinnamaldehyde reacts with hydrochloric acid to produce trifluoroacetic acid, which is then reacted with an organic compound to produce a nitro compound. This reaction has been shown to be irreversible and not sensitive to functional groups. 4-Nitrocinnamaldehyde binds to the enzyme cytochrome P450 reductase, inhibiting its function. The binding of 4-nitrocinnamaldehyde to enzymes such as pyruvate kinase and acetylcholinesterase has also been observed in binding experiments.
