2,4-Dinitrophenol (2,4-DNP)

2,4-Dinitrophenol (2,4-DNP) is supplied as a laboratory-grade crystalline solid at ≥99 percent purity, wetted with water for stability in storage and handling. It is a toxic nitroaromatic intended for research use in institutional, university and industrial laboratories.

2,4-DNP is the classic mitochondrial uncoupler used in cellular bioenergetics work on oxidative phosphorylation, proton gradients, reactive oxygen species and calcium handling. It also serves as a hapten in immunoassay and detection systems, as a pH indicator, as an intermediate in dye and photochemical synthesis, and as a reference compound in environmental studies of nitroaromatic pollutant degradation.
