5-Nitrofurfural (NFA) an important photodecomposition product and metabolite of medicinal nitrofurans is phototoxic in bacterial test systems. Its major photodecomposition product 5-hydroxymethylene-2(5H)-furanone (HMF) appears to be responsible for this. Furthermore HMF and photoactivated nitrofurfural can induce repairable DNA damage in

5-Nitro-2-furaldehyde (NFA) forms in alkaline solutions an anion of nitronic acid of (5-nitro-furan-2-yl)-methanediol. Upon acidification (5-nitro-furan-2-yl)-methanediol (HNFA) appears with pKa=4.6. Then, in a novel irreversible redox ring-opening reaction, nitrile oxide of alpha-ketoglutaconic acid is formed which hydrolyses in acidic solutions.
