It dissolves slightly in water. DNP present in water and soil as a pollutant does not easily evaporate to air. It uncouples oxidative phosphorylation by carrying protons across the mitochondrial membrane, leading to a rapid consumption of energy without generation of ATP. 2,4-DNP was used in the 1930s as a weightreduction drug, but this was discontinued in 1938 because of the many reports of adverse effects in people who used it.
