Trinitrophenols

In chemistry, the trinitrophenols form a group of aromatic compounds that are derived from both phenol and nitrobenzene . The structure consists of a benzene ring with an attached hydroxyl group  (-OH) and three nitro groups  (-NO ₂ ) as substituents . Their different arrangement results in six constitutional isomers with the empirical formula C ₆ H ₃ N ₃ O ₇ , of which 2,4,6-trinitrophenol (picric acid) is by far the most important.
