<p>3-Hydroxy-2-nitrobenzonitrile (3HNB) is a biomolecule that has been systematically studied. It is a cyclic molecule with two nitro groups, and is synthesized by the reaction of 3,4-dihydroxybenzonitrile with nitric acid. The crystal structure of 3HNB was determined by X-ray diffraction to be orthorhombic and space group Pbca. The kinetic and thermodynamic parameters of 3HNB have been investigated in tumour cell lines. Mechanistic studies show that it inhibits the proliferation of tumour cells by binding to DNA and inhibiting DNA synthesis. This inhibition leads to cell death via apoptosis or necrosis, depending on the concentration of 3HNB used.</p>

2-Bromo-4,6-difluorobenzaldehyde is an aromatic aldehyde that can be used as a reagent in the olefination of benzylic alcohols. This process involves the formation of an alkylidene derivative from an alkoxybenzene and an aldehyde. The reaction is catalyzed by palladium or nickel, which act as intramolecular oxidants. The resulting product is a ketone with two adjacent carbon atoms on one side of the double bond. 2-Bromo-4,6-difluorobenzaldehyde has been found to be more efficient than other types of aldehydes for this purpose because it does not require protection of the hydroxyl group during the reaction.
