1) Even the poisonous dinitrophenol made a comeback.

2) One of the early ones was dinitrophenol, the first synthetic drug used for weight reduction.

3) Dinitrophenol, when applied to the leaf, reduced sucrose transport.

4) The second order nonlinear optical material, 2,4 dinitrophenol ( DNP ) was synthesized.

5) In the presence of acid and polyethylene glycol, phenol reacted with ceric ammonium nitrate 2, 4 - dinitrophenol.

6) A novel method has been set up for the determination of 2,6- dinitrophenol , 2,4- dinitrophenol and picric acid in industrial wastewater by highly efficient liquid chromatography.

7) To study the antipyresis of Shenglongqinlong Decoction (SLQLD), SLQLD without Plaster stone and SLQLD without lumbricus, fever models of E. coli endotoxin and 2,4 dinitrophenol were employed.

8) In the differential pulse voltammetry grams(DPV), the o-nitrophenol, 2,4- dinitrophenol and 2,4,6-trinitrophenol were observed respectively to have one, two and three sensitive deoxidize peaks.
